90L comes close to being the season's first named storm
Posted by: Dr. Jeff Masters, 23. toukokuuta 2009 klo 17:30 (GMT) +2
The large extratropical storm (90L) that has been pounding Florida, the Bahamas, and Haiti this week with heavy rain and high surf has moved ashore over Mississippi. Last night and this morning, the storm put on an impressive burst of heavy thunderstorm activity and came close to becoming a subtropical or tropical depression. Winds at the Fort Morgan, AL station were 44 mph, gusting to 52 mph, and winds at Dauphin Island, Alabama coastal station were sustained at 39 mph, gusting to 48 mph at between 8am and 10am EDT this morning. While these winds were in excess of the 39 mph threshold of tropical storm force, both measurements were taken at elevations higher than the international wind measurement standard of ten meters, so the top measured winds of 90L were actually slightly less than tropical storm force. Had 90L spent another six hours over water, it very likely would have been declared a tropical/subtropical depression/storm.

The circulation around 90L continues to mean rain for Florida, but the rains will be lessening today. Rainfall amounts as high as 28 inches were measured this week in Northern Florida at Brunnell. Rainfall amounts of 2 - 3 inches have accumulated along the Alabama, Mississippi, and Florida Panhandle coasts from 90L so far (Figure 1).

There are no other threat areas in the Atlantic to discuss today, so have a great weekend, and I'll have a new blog post by Tuesday.

Dude? Blob? kind of early for Rum isn't it?

Good Morning Folks....Thinking it will be quiet in the tropics for next few weeks, as it should be, this early in the year (after all of the recent excitement in the Gulf)...That Bahamas area seems to have lost it's "spunk" this morning.......However, don't know if the models are looking at anything in terms of the area of convection about to leave Texas into the Gulf but shear levels are pretty high in that region right now.

Comebacks...

(1)Those are early model runs. They could change on the next set.

(2)What's a "fish" storm?

(3)I hate it when someone says fish storm.

(4)You're forgetting Bermuda.

(5)Could it loop back and hit.....

(6)Could the high build in and force it back west.

In all seriousness, it does look headed out-to-sea.

I'm more interested in the SE Texas and Mexico "blob".

Blob...from wordweb..."An indistinct shapeless form"

91L has a better chance to develop then 90L (Unnamed Tropical Storm) because wind shear with 91L is more favorable.. the only thing thats slowing it down is cooler water temps.. thats the only thing.

Seems as though the NHC isn't as conservative as they were last year. I remember many screaming that storms last year should be Invests and it would take days for them to issue one.

By the way, good mornin all

Xtrap isn't a model ! 91L has no chance to even be an STD so I am not sure why this one got tagged.

90L gave the east coast great waves-yesterday 3-4' and glass until noon. But water temps are low, at Ponce it was 75, but only the first few inches felt that, as I paddled I could really feel the colder water below. So this location not quite ready for prime time yet. Of course, being 58 years old, what was once warm, is now cold!!

I think that is because both of these were close to HOME.

Whats your reason?? Shear is low.. the only thing that could inhibit any development would be cooler water temps. Know your facts..
Shear is 5-10 knots over the storm and dry air is not in that area.
