A trio of tropical threats has emerged in the Atlantic basin, forecasters warned.
Newly named Tropical Storm Imelda is threatening to swamp portions of southeastern Texas with up to a foot of rain this week, possibly leading to dangerous, life-threatening flash floods.
Enough rain is forecast to fall to cause significant street, highway and low-lying area flooding along the Gulf Coast of Texas, AccuWeather said. This includes the cities of Beaumont, Houston, Galveston, Matagorda, Victoria and Corpus Christi, Texas.
"Rainfall rates of 1 to 3 inches per hour and potentially saturated soils from the precipitation that falls today will continue the threat of flash flooding into Thursday," the National Weather Service in Houston said.
Tropical Storm Imelda, Hurricane Humberto and Tropical Depression Ten were all spinning in the Atlantic Basin on Tuesday, September 17, 2019.
A flash flood watch has been posted across the entire Houston metro area, the weather service said.
In addition to the likelihood of flooding, some of the thunderstorms can be robust with strong wind gusts, according to AccuWeather. A couple of the strongest thunderstorms can produce a waterspout or tornado.
Even though it's only a tropical storm, it can still be a big threat. Some of the most disastrous flooding in that region has come from storms that were no longer hurricanes like Tropical Storm Allison in 2001 and the remnants of Hurricane Harvey in 2017, noted University of Georgia meteorologist Marshall Shepherd.
