90L comes close to being the season's first named storm
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.

i dont think charleston will have any problems past tomorrow cause the system will be to your north
yea, if it moves a little faster. If it moves a little more quickly the chances of it moving more east is diminish. If it moves slowly, the high will build enough west to allow a more easterly track. Much of the convection however remains east of the center regardless of motion. It should clear the area by Thursday
I'm still without DSL internet here. I think my modem got fried yesterday. When I got home from work for good last night, after 10 p.m., our power was still off. Additionally, my phone line was dead, so I couldn't even use that to get online [shudders]. If it's this bad after a Tsstorm, what'll happen in a genuine hurricane?
What's the prognosis on our trough / low? We actually had a visible sunrise today (1st in days), so I'm assuming it's beginning to pull out to the north. Local mets are expecting continued afternoon showers, though, so I'm assuming the overall situation remains unstable.
not bad i'll give it a B- as far invets or disturbences
Where is my medication?! LOL
Good Morning!
