A weakening Bill generating a major wave event for Bermuda and the U.S. coast

Wind shear and dry air are weakening Hurricane Bill, which may no longer be a major hurricane. However, the hurricane is still large enough and strong enough that it will generate a major wave event for much of the Western Atlantic. Visible and infrared satellite imagery show that the hurricane is no longer as symmetric as it once was, with a squashed oval shape to its cloud pattern. Upper-level cirrus clouds are restricted on the storm's southwest side, indicating that upper-level winds from the southwest are shearing the storm. The University of Wisconsin CIMSS wind shear analysis shows about 10 - 15 knots of southwesterly wind shear impacting Bill. Satellite intensity estimates of Bill's strength show essentially no change since 2am EDT this morning, and Bill is at the borderline of becoming a Category 2 hurricane. There are currently no Hurricane Hunter aircraft in Bill, and the next mission is scheduled for 2pm EDT this afternoon.

Wind shear is forecast to remain low to moderate, 5 - 15 knots, for the next two days, and it is possible Bill may see a relaxation of the wind shear affecting it, allowing some re-intensification today. Sea Surface Temperatures (SSTs) will be plenty warm today, as Bill traverses a region of ocean with SSTs near 29°C. Total ocean heat content is steadily declining, though, as the warm waters Bill is currently traversing do not extend to great depth. By Saturday, SSTs decline to 27.5°C, and intensification becomes less likely.


Figure 1. Visible satellite image of Bill at from Friday morning 8/21/09. Bill had an oval shape, and was missing upper-level cirrus clouds on the southwest side, indicating that wind shear from strong upper-level southwesterly winds was affecting it.

The computer model track forecasts for Bill have been very consistent the past two days, giving confidence that the trough of low pressure developing along the U.S. East Coast this weekend will turn Bill to the north then northeast as expected. Both Nova Scotia and Newfoundland, Canada can expect tropical storm conditions from Bill, which should be rapidly weakening on Sunday afternoon when it makes its closest pass to Nova Scotia. Category 1 hurricane conditions are possible on Nova Scotia if Bill makes a direct hit there. Cape Cod and eastern Maine may receive sustained winds of 35 mph from Bill, just below tropical storm force, but the chance of a direct hit by Bill are slim.

Bill's waves
Hurricane Bill is generating huge waves, thanks to its enormous size and major hurricane intensity. Output from NOAA's Wavewatch III model suggests that significant wave heights near Bill's center will peak at 50 feet by Saturday. Large swells from Bill have reached Bermuda, and are generating waves of 10 - 20 feet in the offshore waters. The Bermuda Weather Service predicts seas will increase to 20 - 30 feet on Saturday as Bill makes its closest approach to the island.

In the U.S., Bill's swells will reach New York's Long Island on this afternoon, and seas will build to 7 - 10' on Saturday and 12 - 16' on Sunday in the near shore waters. By tonight, Bill's swells will be affecting the entire U.S. East Coast from Florida to Maine. Maximum sea heights in near shore waters over the weekend will be about 6 - 8' from Florida to South Carolina, 11 - 14' along the North Carolina coast, 8 - 11' along the mid-Atlantic coast, and 11 - 14' along the coast of Maine. The highest waves along the U.S. coast will occur at Cape Cod, Massachusetts, where waves of 18 - 23' are being forecast by NOAA for Sunday. Bill's high waves will likely cause millions of dollars in coastal erosion damage and create very dangerous rip currents and swimming conditions along the coast.

CloudSat slices through Bill
The CloudSat satellite, launched in 2006, carries the first satellite-based millimeter wavelength cloud radar. It is the world's most sensitive cloud-profiling radar, more than 1000 times more sensitive than current weather radars. It collects data about the vertical structure of clouds, including the quantities of liquid water and ice, and how clouds affect the amount of sunlight and terrestrial radiation that passes through the atmosphere. The satellite has a narrow field of view, so can image only a small portion of the planet each day. About once per year, CloudSat happens to slice through the eye of an Atlantic hurricane. This happened Wednesday, when CloudSat caught a remarkable view of Hurricane Bill (Figure 2).


Figure 2. Top: conventional 89 GHz microwave "radar in space" image of Hurricane Bill on Wednesday, 8/19/09, from the AMSR-E instrument on the Aqua spacecraft. Bottom: cross section through Bill's eye taken at the same time from the CloudSat cloud radar instrument. The CloudSat pass occurs along the red line in the top image. The CloudSat pass runs from south (left side of CloudSat image) to north (right side of CloudSat image). At the time of the image, Hurricane Bill was strengthening into a Category 4 hurricane (135 knot winds, 947 mb pressure), while completing an eyewall replacement cycle. In the 89 GHz Microwave image, half of the eyewall is already completed (half red circle on right side of the image). In the CloudSat image, the southern eyewall shows weak echoes at the low levels, and slopes outward with height. The northern eyewall is much more intense, and a core of high reflectivity echoes extends high into the troposphere, to 16 km altitude, forming a "hot tower". These "hot towers" a characteristic of intensifying hurricanes. Interestingly, the hot tower is tilted into the eye, so that the eyewall does not slope outward with height along the northern eyewall. This is not the typical behavior of a hurricane, and may be due to the unusual strength of the hot tower. Cirrus clouds with a base at 8.5 km can be seen to the south of the hurricane in the CloudSat image. The thin grey line at 5 km marks the 0°C temperature line. Ice particles falling inside the hurricane melt at an altitude just below the 0°C line, creating a "bright band" of orange echoes throughout most of the hurricane.

Elsewhere in the tropics
There are no threat areas in the Atlantic worth mentioning today. The GFS model calls for a tropical cyclone to develop just off the coast of Africa about seven days from now.

I'll have an update Saturday.

Reed, please, GIVE IT UP


You should give it up.....In my observation of thie blog Reedzone hascontributed much more and been much more accurate with giving possible scenario setups than anything I have seen posted by you.

What he stated was accurate...if that trough would have been delayed the impact on the northeast could have been a major event.

Early models are used by NHC for their forecasts. From the 2008 Season Verification Report

Numerous objective forecast aids (guidance models) are available to help the
NHC in the preparation of official track and intensity forecasts. Guidance models are
characterized as either early or late, depending on whether or not they are available to the
forecaster during the forecast cycle. For example, consider the 1200 UTC (12Z) forecast
cycle, which begins with the 12Z synoptic time and ends with the release of an official
forecast at 15Z. The 12Z run of the National Weather Service/Global Forecast System
(GFS) model is not complete and available to the forecaster until about 16Z, or about an
hour after the NHC forecast is released. Consequently, the 12Z GFS would be
considered a late model since it could not be used to prepare the 12Z official forecast.
This report focuses on the verification of early models, although some late model
information is also given.


Thanks so much for your response.

Good morning all. Thanks to everyone for their answers to my questions about predictions for Halifax for the last week. I'm presently on duty on one of the Canadian Warships docked in Halifax harbour, and thanks to the wunderground I have been well prepared for bill since Tuesday. Well before the rush took place around here to fill up on water and fuel etc.
It seems like Bill won't be as severe as origionally thought for Halifax and I for one am very happy about that. Let's hope tomorrow is only a tropical storm event for us and not a repeat of Juan.
To the folks who were screaming all week that Bill was headed towards the Carolina's, New England, or in one case NYC. I have a new hatred of wishcasters. I noticed all those folks have gone back to lurking and hopefully the comments trail stays a little "cleaner" for the next couple of days.
I makes a fellow wonder are some of the "wishcasters" out there hoping for a major hurricane to hit their city? Is that what they want to happen? Having been through a hurricane or two both at sea and on shore, the last thing someone in this world should hope for is a damaging storm endangering thier neighbour and friends. I hope in future those folks think of that when they yell "Hey it's turning towards me!" on the hope that they are in line for a hit from a major storm.
Sorry for the rant wunderground, if Bill is a non event for Halifax then I will go back to lurking as well. Thanks wund folks for giving this fellow an excellent heads up on this storm and making my family better prepared.
keep in mind a lot of people posting the wishcasting are kids who truly have no understanding. They don't see the real piture of a damaging storm, just the possible days off from school.

IMO we may have another Central Pacific tropical storm based on how close 92L is to the basin. What's the record for most tropical storms in the C. Pacific?

Also, I give the yellow circled wave in the atlantic a 40-60% chance of becoming a TD.

My guess is that the t-wave near 35W won't develop for now, due to the trough/ULL which has dipped southward to the southeast of Bill. The center of the ULL appears to be at about 50W and 27N and still appears to be drifting further south or southwest. This should create an unfavorable environment for the t-wave to get better-organized.

They must have a different map to look at than I do



Good morning StormW

From looking at the shear map I do see some fast SW winds to the NW near where the low will be at 40W. Given its current disorganized state even marginally high wind shear will likely serve to hamper development. Perhaps it is that which the NHC are referring to even though for the moment the wave is sitting under a high.

Wednesday through Sat...moisture will be on the return and with either an
upper low or at least a weakness in the middle levels scattered convection
should start to affect most of the region especially during the
afternoon. Temperatures will also be back around normal. Still need to keep an
eye out as our front will dissipate over the Gulf add in that there
could be a weak upper low over the Gulf and either of those can
always lead to some tropical development this time of the year.

Area forecast discussion
National Weather Service New Orleans la
419 am CDT Sat Aug 22 2009


..cold front moving through this morning...


Short term...the cold front is currently working its way to the
coast stretching from northestern Alabama SW twrds southwestern la. The front will
continue to slowly work south twrds the coast this morning and by
midday should be through all of our coastal waters. Most of the
convection has come to an end overnight but there were still isolated
storms along the front mainly b/T lft and btr.


Today...look for isolated/scattered convection to refire later this morning
as the front continues to push south and another disturbance moves
down in the SW flow aloft. This activity will be along and south of
the front mainly across our coastal waters. Behind the front much
drier air will start to work in from the north but the cooler air
will lag back by about 12 hours or so. With that highs will mainly be
around 90 across most of the area but with less humid conditions
today it will be more comfortable. All rain should be at least 60 nm
south of the coast by early/middle afternoon with rain likely not returning
until late Tuesday if not Wednesday.


Sat night through Tuesday...quieter and much more comfortable conditions
expected across the region. Dewpoints will drop into the upper 50s
across our northern zones and middle 60s as far south as the la coast. Skies
will clear out late tonight with mostly clear to clear skies
expected to persist through Tuesday. Winds will also be relatively light
most nights...with tonight being an exception. Some cold air advection in the ll
tonight along with winds around 15kts just above the surface should keep
the surface winds from going calm...likely staying up in the 5-10kt
range. This will Hurt radiational cooling tonight but look for lows
to still be a good 5-10 degrees cooler than this morning. Over the
next few nights winds should be rather light and with dry conditions
over the region along with clear skies lows should be able to drop
nicely with possible upper 50s across southern MS and in the Pearl River
and Pascagoula drainage basins Sun night. H925 temperatures will fall to
20-21c sun then rise about a degree each successive day leading to
mostly upper 80s tomorrow and lower 90s by Tuesday. As for rain...we
should remain mostly dry but by Tuesday moisture will try to work back
twrds the region. In addition to that as the eastern Continental U.S. Trough
flattens out a piece of it may cut off/detach over the northern/northwestern Gulf
Tuesday and this could help get isolated convection across the coastal
waters Tuesday afternoon. /Cab/


Long term...no big changes in the thinking for the extended. There
are some differences in the medium range with how they handle that
piece of middle level energy over the northwestern Gulf. The European model (ecmwf) is stronger
with this feature and pushes it west into southern Texas while the GFS is
weaker and keeps it over the lower MS valley. For the most part our
sensible weather will be similar either way so I will just stick
with the GFS/mex at this time.



Wednesday through Sat...moisture will be on the return and with either an
upper low or at least a weakness in the middle levels scattered convection
should start to affect most of the region especially during the
afternoon. Temperatures will also be back around normal. Still need to keep an
eye out as our front will dissipate over the Gulf add in that there
could be a weak upper low over the Gulf and either of those can
always lead to some tropical development this time of the year.

First, my point is that he has been touting a NY hit long before Bill was formed. Second, if the troughs were delayed or Bill's spped was different, it could have put a lot of places in harms way, from the Lerrers all the way up to Maine, NOT just NYC.

It isn't missing data, it just doesn't show temps below about 26C which is the cut off for supporting TC.

Quoting leftovers:
they sure overestimated the swells e central florida 4-6 ft max maybe alittle bigger occasionally these waves were mostly closed out


NOAA completely blew the wind forecasts in PR, up to the same day. Major letdown.

No problem with dry air currently, as opposed to Ana/Bill:

Quoting reedzone:
You can see how much of a close call this really was from a Historic East Coast storm. If the trough came in a day late, Bill would have been easily 100-200 miles more west and moving into Long Island, NY.

Reed, please, GIVE IT UP
