Flash Flood Warnings are being issued for coastal counties in Texas and Louisiana near theis system

From Dr. Jeff Masters:

The area of disturbed weather 100 miles south of Freeport, Texas (90L), has become well-organized this morning, and a tropical depression appears to be forming. . .

Long range radar out of Houston shows a well-defined surface circulation exists about 100 miles south of Freeport, with some low-level spiral bands starting to get organized. A ship just east of the center measured 40 knot (46 mph) winds at 8am EDT, but this is likely a strong downburst wind from a thunderstorm, and is not representative of the larger-scale winds. A buoy 70 miles south of Freeport measured sustained winds of 25 mph at 8:50am EDT. Wind shear is a low 5-10 knots, and 90L does have time to develop into a tropical storm before it makes landfall tonight or Thursday along the mid or upper Texas coast. Since this system is very slow moving, it has the potential to drop rain amounts in excess of ten inches along the Texas and Louisiana coasts--including the Houston metropolitan area--over the next two days. These rains may cause serious widespread flooding. Rainfall amounts of 2-3 inches have already occurred along the coast, from Freeport to the Louisiana border, as estimated by radar.

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

1. SHOWERS AND THUNDERSTORMS HAVE BECOME A LITTLE MORE CONCENTRATED INASSOCIATION WITH THE BROAD AREA OF LOW PRESSURE LOCATED ABOUT 1200MILES EAST OF THE WINDWARD ISLANDS. CONDITIONS APPEAR FAVORABLE FORTHIS SYSTEM TO DEVELOP INTO A TROPICAL DEPRESSION WITHIN THE NEXTDAY OR SO AS IT MOVES WEST-NORTHWESTWARD AT 5 TO 10 MPH.

2. SHOWER AND THUNDERSTORM ACTIVITY ASSOCIATED WITH A BROAD LOWPRESSURE AREA LOCATED OVER THE NORTHWESTERN GULF OF MEXICO HASDIMINISHED THIS EVENING. HOWEVER...ENVIRONMENTAL CONDITIONS APPEARCONDUCIVE FOR SOME DEVELOPMENT OF THIS SYSTEM AS IT DRIFTS SLOWLYWEST-NORTHWESTWARD OVER THE NEXT DAY OR TWO.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THENEXT 48 HOURS.
