Tropical Depression Imelda Discussion Number   3
NWS National Hurricane Center Miami FL       AL112019
1000 PM CDT Tue Sep 17 2019

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

Key Messages:

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