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.

NASA High-Resolution Visible loop of the Bahamas
Mid-level circulation continuing to develop. Dry air is getting punched into the west side of the system by the sub-tropical jet, as evidenced by the lack of low-level cloud streets to the west of the system, which you can see clearly in the loop.
lol....NASA does not have rapid scan =P
How did you save the animation or its settings seperate from the webpage.
Lol I know, just teasing yah.
The RAMSDIS floaters update as fast as 5 mins after the image is taken, I can't imagine WeatherTap updating any faster than that. Nasa is also pretty fast.
This does though lol (when a storm is active)
Nasa used to have rapid-scan, I don't understand why it doesn't anymore this year. It still updates every 15 mins though which isn't bad.

another low to form from the monsoon?
Which cell?
Composite overdoes the intensity of the cells greatly. Not really that good...
Never saw that...thanks.
23 tends to be very bearish and responsible with his predictions. Facts over hype, fear or wishcasting. Him feeling this way makes me a little uneasy.

Very true.
At least nine people were killed in Bangladesh, and dozens of people are still missing. More than 300,000 people there have been trapped by the high water levels. In India, more than a hundred thousand people have been forced to evacuate their homes.
Heavy rainfall and high waves have flooded hundreds of coastal villages in both countries, dams have broken and many rivers have burst their banks.
I'm headed back to work right now, while the rain seems to be holding up. If we have power there, and if I get onto the wireless system, I'll check in when I get there.
Later.
