Tropical Storm Nicholas, which popped up in the Gulf of Mexico over the weekend, is expected to make landfall on Texas' Coastal Bend sometime this afternoon or evening, according to the National Hurricane Center.
Much of East Texas remains in the storm's cone of uncertainty, meaning the weakened center of Nicholas could pass over the region sometime after landfall.
According to the National Weather Service, there is a 10 to 20 percent chance that East Texas could experience tropical storm-force winds at some point over the next three days. The NWS says the earliest likely arrival time of any tropical storm force winds in East Texas would be around 8 a.m. Tuesday, though winds could arrive sooner, depending on the speed of the storm.
The National Weather Service office in Shreveport said Nicholas could lead to heavy rain and isolated flash flooding across the southern counties and parishes in East Texas and North Louisiana.
Given the current track, the threat for heavy rainfall and possible flash flooding may become more of a concern across parts of lower East Texas and North Central Louisiana by mid- to late week, according to the NWS Shreveport office. They added that depending on later storm track and intensity, this threat could also expand farther north to include more of the region up to the Interstate 20 corridor. In addition, some weak and short-lived tornadoes may also be possible; as is the case with any inland tropical system.
Projected East Texas rainfall from Nicholas ranges from a half-inch to an inch in Tyler and Longview to upwards of 3 inches possible in Lufkin. The Shreveport office says the threat of heavy rainfall and flash flooding will increase later this week with the remnants of Nicholas. Expect as much as 3-6 inches of rainfall to be possible over Deep East Texas into parts of North Central Louisiana through Friday.
