As of the morning (local time) of Thursday, September 19, significant and life-threatening flash flooding is ongoing across portions of southeastern Texas state due to the passage of Tropical Depression Imelda. In Chambers and Jefferson counties, floodwaters have reportedly submerged roads and caused significant transportation disruptions, forcing closures along sections of Interstate 10 and US 90 highways. The flooding has also reportedly trapped a number of people inside vehicles and homes, and rescue operations are underway across affected areas. Significant disruptions, including delays and cancelations, have been reported at George Bush Intercontinental Airport (IAH) and Beaumont Municipal Airport (BMT). Flash flood warnings are also in effect for parts of southwestern Louisiana state, notably in Cameron Parish, Lake Charles, and Vernon Parish. Additional rainfall of 12-25 cm (5-10 in) is forecast in southeastern Texas state and 5-15 cm (2-6 in) in southwestern Louisiana state through Thursday evening.
As of 04:00 on Thursday, the center of Imelda is located at approximately 31.3°N, 95.5°W and is tracking north-northwestward at 7 kph (5 mph). Imelda has maximum sustained winds of 45 kph (30 mph) and is expected to gradually weaken during the next 24 hours. Associated power outages and disruptions to transportation and business services are to be expected in areas forecast to be affected by the storm over the coming hours and days.
Individuals in areas forecast to be affected by Tropical Depression Imelda are advised to monitor local weather reports, confirm flight reservations, adhere to instructions issued by local authorities, anticipate adverse weather and power and transportation disruptions, and remember that running water can be dangerous - 15 cm (6 in) is enough to knock over an adult - and never drive through flooded streets; floodwater may also contain wastewater and chemical products.
