Flood Watch

* WHAT...Flooding caused by excessive rainfall continues to be possible.

* WHERE...A portion of southeast Texas, including the following areas, Brazos, Grimes, Houston, Madison, Montgomery, Northern Liberty, Polk, San Jacinto, Southern Liberty, Trinity and Walker.

* WHEN...Through Thursday afternoon.

* IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Flooding may occur in poor drainage and urban areas.

* ADDITIONAL DETAILS... - A swath of very high rainfall totals over portions of Liberty, Polk, San Jacinto, Montgomery, and Trinity Counties has saturated the ground. Rainfall has not been as significant further to the west and northwest. That said, periods of showers and thunderstorms are anticipated into Thursday in association with the remnants of Edouard. Embedded, training rain rates between 2-4 inches per hour are possible in this deep tropical airmass. Where this occurs, especially over the already hardest hit areas, rainfall will rapidly runoff to produce flash flooding. - http://www.weather.gov/safety/flood
