Full Notification

* WHAT...Flash flooding caused by excessive rainfall is possible. Areas of poor drainage closer to the coast are most at risk, particularly more urban areas.

* WHERE...A portion of southeast Texas, including the following areas, Bolivar Peninsula, Brazoria Islands, Chambers, Coastal Brazoria, Coastal Galveston, Coastal Harris, Coastal Matagorda, Fort Bend, Galveston Island, Inland Brazoria, Inland Galveston, Inland Harris, Inland Matagorda, Matagorda Islands, Southern Liberty and Wharton.

* WHEN...The watch is in effect through Friday evening. The greatest concern today will be on the immediate coast, expanding across the rest of the watch area later tonight into Friday.

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

* ADDITIONAL DETAILS... - A poorly organized area of showers and thunderstorms over the northwestern Gulf of Mexico are beginning to impact the immediate Southeast Texas coast this morning. This low pressure area is expected to turn northward and move inland later today and drag across Southeast Texas through tonight and Friday. While this area has some potential to become a short-lived tropical depression today, the main threat of heavy rainfall will be the same regardless of whether that happens or not. Drought conditions over the area will mitigate the threat somewhat, but high rain rates in the stronger storms and the duration of the event could still cause flooding issues near the coast in spite of that. Locations most at risk are urban, low-lying, and other poor drainage areas. - http://www.weather.gov/safety/flood
