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.

West to east flow developing over Southeast Florida...T-Storms likely, probably in the interior areas.

Looks like a wet Memorial Day tomorrow.

'mornin' all...

Well, we're proceeding with Phase II of the live webcam / remote weather station test today at XtremeHurricanes.com

PensacolaDoug is about to take over the show from his home in P'cola and operate the system that is ready for deployment and currently stationed in Los Alamos, NM.

I'm "xtreme"ly confident that this is going to work and when it's go-time, our team will be fully prepared to bring you a front-row seat to a U.S. hurricane landfall should one dare come ashore.

Feel free to visit the site during this test. Our goal is to stay up for the entire day.

You may also would like to check out Weather456's blog - History of Caribbean Hurricanes.
Guess he was writing up that blog, which is why we got into that discussion.

When u look at the records, as incomplete as they probably are, there is no way one can say, "That can't happen." There are too many different scenarios in the record to allow for the comfort of absolute exclusions.

Just a bit of trivia along the lines of what 456 and I were talking about last night: the top FIVE sites for hurricane and severe hurricane strikes since the beginning of record-keeping are in The Bahamas!

1 MYAB Abaco (March Harbour), Bahamas 18(4) 40(13) 81(24)
2 MYGF Grand Bahama, Bahamas 15(3) 40(11) 81(26)
3 MYBS Bimini, Bahamas 14(5) 38(12) 72(22)
4 MYNN Nassau, New Providence, Bahamas 14(3) 28(10) 55(17)
5 MYSM San Salvador, Bahamas 13(4) 36(13) 63(18)

Other Bahamian islands are not included, at least in my opinion, because they haven't had as long a record of recorded storms (or no major airport).

Saw a special on the shuttle explosion tragedy. Many years later they are bringing out the role that unusual / unsettled weather had in causing the failure of the fuel tanks.

I don't blame the mets at KSC for their caution.

Next Shuttle landing opportunities in EDT:
Landing: 11:40 a.m., Orbit 197, landing at Edwards (deorbit burn at 10:25 a.m.)

Landing: 11:49 a.m., Orbit 197, landing at Kennedy (deorbit burn at 10:41 a.m.)

California and Florida... NINE minutes of separation (whew)

If (BIG IF) the landing is to take place at KFC, the approach path will be
parallel to, and just offshore of the Gulf coast from Texas to Florida.

Weather at KFC is the focus of many right now!

Tropical Cyclone Warning Number SIX
DEEP DEPRESSION BOB02-2009
11:30 AM IST May 24 2009
======================================

Sub: Deep Depression over west central, adjoining east central and northwest Bay of Bengal and cyclone alert for West Bengal coast.

At 06:00 AM UTC, Deep Depression BOB02-2009 over west central & adjoining east central and north west Bay of Bengal remained practically stationary and lay centered near 18.0N 88.5E, or about 350 kms southeast of Paradip, 400 kms south-southeast of Sagar Island and 470 kms south-southwest of Khepupara, Bangladesh.

The system is likely to intensify further into a cyclonic storm and move in a near northerly direction and cross west Bengal-Bangladesh coast near latitude 89.0E (100 kms east of Sagar Island) around tomorrow evening.

Forecast and Intensity
=======================

Current: 18.0N 88.5E - 30 knots (Deep Depression)
6 HRS: 18.5N 88.5E - 35 knots (Cyclonic Storm)
18 HRS: 20.5N 89.0E - 40-45 knots (Cyclonic Storm)
30 HRS: 21.5N 89.0E - 40-45 knots (Cyclonic Storm)
54 HRS: 23.5N 89.0E - 25 knots (Overland/Depression)

---
estimated times again

*bold in the forecast and intensity indicates the cyclone is close to the coast.

Tropical Cyclone Warning Number FIVE
DEEP DEPRESSION BOB02-2009
8:30 AM IST May 24 2009
======================================

Subject: Deep Depression over west central, adjoining east central and northwest Bay of Bengal and cyclone alert for West Bengal coast

At 03:00 AM UTC, The depression over west central and adjoining east central Bay of Bengal intensified into a deep depression. Deep Depression BOB02-2009 moved northward and lays centered over west central and adjoining east central and northwest Bay of Bengal near 18.0N 88.5E, or about 350 kms southeast of Paradip, 400 kms south-southeast of Sagar Island, and 470 kms south-southwest of Khepupara, Bangladesh.

Satellite imagery indicasts further organization of the system. The dvorak intensity of the system is T2.0. Associated broken intense to very intense convection observed over the Bay of Bengal north of 10.0N and west of 91.0E. The lowest cloud top temperature due to convection is about -80C to the southwest of the system's center.

3 minute sustained winds near the center is 30 knots with gusts of 40 knots and a central pressure of 992 hPa. The state of the sea is very rough around the system's center.

Vertical wind shear of horizontal wind over the region is around 20 knots. The system lies very close to the upper tropospheric ridge, which roughly runs along 19.0N in association with the anticyclonic circulation over Myanmar and adjoining east central Bay of Bengal located to the east-northeast of the system center. There is an upper tropospheric trough in westerlies roughly running along 79.0E to the north of 20.0N. Sea surface temperature are warmer over north and central Bay of Bengal. Majority of NWP models also suggest intensification of the system and landfall over west Bengal and adjoining Bangladesh coast near 89.0E.

Considering all the above, the system is likely to intensify further and move in a near northerly direction and cros West Bengal-Bangladesh coast near 89.0E (about 100 kms east of Sagar Island) between 1200 and 1500 PM UTC tomorrow

Forecast and Intensity
======================
Current: 18.0N 88.5E - 30 knots (Deep Depression)
9 HRS: 19.0N 88.5E - 35 knots (Cyclonic Storm)
21 HRS: 20.0N 88.5E - 40 knots (Cyclonic Storm)
46 HRS: 22.5N 89.0E - 35 knots (Overland/Cyclonic Storm)
58 HRS: 23.5N 89.0E - 25 knots (Overland/Depression)
