Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles.

Please report observed flooding to local emergency services or law enforcement and request they pass this information to the National Weather Service when you can do so safely.

.A new round of heavy rainfall is moving into the area from the northwest very early this morning, and will continue to make its way across Southeast Texas today. An additional 1 to 3 inches of rainfall is expected across broad areas, with isolated higher amounts of 4 to 8 inches possible within the watch area. This may lead to flash flooding, especially in vulnerable areas, and exacerbate already swollen rivers and streams around the area.

...FLOOD WATCH REMAINS IN EFFECT THROUGH THIS EVENING...

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

* WHERE...A portion of southeast Texas, including the following areas, Austin, Brazos, Burleson, Chambers, Coastal Harris, Colorado, Grimes, Houston, Inland Harris, Madison, Montgomery, Northern Liberty, Polk, San Jacinto, Southern Liberty, Trinity, Walker, Waller and Washington.

* WHEN...Through this evening.

* 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. Low-water crossings may be flooded. Extensive street flooding and flooding of creeks and rivers are possible. Area creeks and streams are running high and could flood with more heavy rain.

* ADDITIONAL DETAILS... - A new round of heavy rainfall is moving into the area from the northwest very early this morning, and will continue to make its way across Southeast Texas today. Because of multiple rounds of heavy rain over the past week, flooding may be seen earlier than would be expected under typical conditions. Rainfall today will continue to exacerbate existing river flooding. - http://www.weather.gov/safety/flood
