1. This system is likely to produce life-threatening flash flooding along portions of the Upper Texas Coast, including the Houston and Galveston areas.

SUMMARY OF ALERTS:

There are no coastal watches or warnings in effect.

RAINFALL: [TOP] Imelda is expected to produce total rainfall accumulations of 6 to 12 inches with isolated maximum amounts of 18 inches across the upper coastal region of Texas, including the Houston and Galveston areas. Rainfall amounts of 4 to 6 inches with isolated totals of 10 inches are possible across portions of southeast Texas and southwest Louisiana through Thursday. This rainfall may produce significant to life-threatening flash floods.

At 1000 PM CDT (0300 UTC), the center of Tropical Depression Imelda was located near latitude 29.8 North, longitude 95.5 West. The depression is moving toward the north near 6 mph (9 km/h) and this general motion is expected to continue for the next couple of days. On the forecast track, Imelda will move over eastern Texas through Thursday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Gradual weakening is forecast during the next 48 hours, and the system should become a remnant low by late Thursday.

The estimated minimum central pressure is 1007 mb (29.74 inches).

The center of the tropical cyclone continues to move farther inland over southeast Texas, with a motion estimate of 360/5 kt. Earlier surface observations along the coast indicated that the intensity had dropped below tropical storm strength, so the Tropical Storm Warning was discontinued.

Although it has weakened, slow-moving Imelda will remain a rainfall/flood threat for at least the next couple of days.

This is the last NHC advisory on Imelda. Future information on this system can be found in Public Advisories issued by the Weather Prediction Center beginning at 5 AM EDT, under AWIPS header TCPAT1, WMO header WTNT31 KWNH, and on the web at http://www.wpc.ncep.noaa.gov.
