Full Alert Message

URGENT - IMMEDIATE BROADCAST REQUESTED Flood Watch National Weather Service Houston/Galveston TX 110 AM CDT Wed Jun 17 2026 ...FLOOD WATCH NOW IN EFFECT THROUGH THIS EVENING... * WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...Portions of south central and southeast Texas, including the following areas, in south central Texas, Coastal Jackson and Inland Jackson. In southeast Texas, 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, Montgomery, Northern Liberty, Southern Liberty and Wharton. * WHEN...Through this evening. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Extensive street flooding and flooding of creeks and rivers are possible. * ADDITIONAL DETAILS... - Coastal areas will have the greatest potential for flooding through this afternoon as Potential Tropical Cyclone One skirts along the Upper Texas Coast. Rainfall rates could exceed 4 inches per hour in the heaviest downpours. Additional widespread rainfall amounts of 2 to 4 inches in the watch area with isolated higher totals possible especially along the coast. Grounds are fairly saturated across portions of Southeast Texas, which would allow for a quicker transition of the rainfall to runoff. This increases the potential for flooding, especially in the areas that have received 4+ inches of rain over the past few days. - Http://www.weather.gov/safety/flood PRECAUTIONARY/PREPAREDNESS ACTIONS... You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
