Potential impacts to southeast Texas include the prospect of locally heavy rainfall and flash flooding, 1-3 feet of coastal flooding across the coast and along the bays, and gusts to tropical storm force along the immediate coast. Impacts will persist through today before diminishing this evening as the system lifts to the northeast of the area. A Tropical Storm Watch remains in effect for all coastal areas of SE Texas and the Gulf waters out 60 nm, with the exception of Matagorda Bay. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Prepare for dangerous rainfall flooding having possible significant impacts across portions of southeast Texas. Potential impacts include: - Moderate rainfall flooding may prompt several evacuations and rescues. - Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, canals, and ditches overflow. - Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures. Prepare for locally hazardous rainfall flooding having possible limited impacts across the northern Brazos Valley and Piney Woods Region. Elsewhere across Southeast Texas, little to no impact is anticipated. * SURGE: Coastal flood warnings and advisories have been issued for the immediate coast. Please reference the Coastal Hazard Message for more information. Potential impacts in this area include: - Numerous roads may be closed. Low lying property including homes, businesses, and some critical infrastructure could be inundated. Some shoreline erosion will occur. Elsewhere across Southeast Texas, little to no impact is anticipated. * WIND: Little to no significant impacts are anticipated at this time across Southeast Texas. * TORNADOES: Prepare for a tornado event having possible limited impacts across coastal portions of southeast Texas. Potential impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings. Elsewhere across Southeast Texas, little to no impact is anticipated. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials. * OTHER PREPAREDNESS INFORMATION: If you live in a place particularly vulnerable to flooding, such as near the ocean or a large inland lake, in a low-lying or poor drainage area, in a valley, or near an already swollen river, plan to move to safe shelter on higher ground. Always heed the advice of local officials and comply with orders that are issued. Do not needlessly jeopardize your life or the lives of others. Closely monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information. Listen for possible changes to the forecast. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Houston/Galveston TX around 10 AM CDT, or sooner if conditions warrant.
Flood Watch
Issued: 6:10 AM Jun. 17, 2026 – National Weather Service
...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. &&
