Harvey’s track coming closer to South Mississippi

National Weather Service

Tropical Storm Harvey is veering more and more eastward, and the National Hurricane Center track on Tuesday forecast the storm to move toward North Mississippi after making landfall near the Texas-Louisiana border.

The new track brings more risk for heavy rainfall to coastal Mississippi.

Harvey is still moving very slowly, dumping extreme levels of rain near Houston and southwest Louisiana. The storm’s center has moved just off the Texas coast, and it’s sending bands of rain out across southern Louisiana and Mississippi.

Rain began to fall in South Mississippi late Monday, and remained spotty through Tuesday as rain bands moved across the area. All it takes is one band of rain to dump several inches of rain in a short period to cause flash flooding. The weather service warned one TV station reported 1.5 inches in just 15 minutes on Monday.

The Weather Prediction Center noted there is “very moist and unstable air around the East side of Harvey,” that has elevated the risk of severe weather. There is a slight risk of severe storms with tornadoes Tuesday.

The weather service also warns that dry air mixing with the storm and keeping heavy rainfall at bay won’t reach Mississippi, so the Coast has a high likelihood of heavy rainfall of 5 to 8 inches on Wednesday. Chances of rain drop off significantly Thursday.

A flash flood watch is in effect through Thursday for Hancock, Harrison, Jackson and Pearl River counties. Rainfall amounts of 5 to 10 inches are possible, and as much as 2 to 3 inches per hour could fall. There is also a coastal flood advisory through Thursday evening.

Tuesday morning, a flood warning was issued for the Biloxi River near Lyman in Harrison County. The river is forecast to rise above flood stage, 12 feet, by late Wednesday and continue to rise until is crests at about 13 feet by Thursday morning.
