The light rain Southeast Texas received Saturday will be nothing compared to the heavy rainfall expected to hit early next week.

The National Weather Service in Lake Charles, La. is forecasting five to six inches of rain in the Beaumont-Port Arthur area early next week from an incoming tropical system developing over the Yucatan Peninsula.

The storms over the Yucatan are expected to form more of a unit and move northwest through the Gulf of Mexico, aiming toward Houston when the system reaches landfall, NWS Meteorologist Tim Humphrey said Saturday afternoon.

“That system currently has a 50 percent chance of becoming a tropical storm within the next five days,” Humphrey said. “But regardless of whether this does become a tropical storm with a name or just comes in as groups of storms, Southeast Texas will see heavy rain Monday evening through Wednesday morning.”

Humphrey said along with a potential for streets flooding, Southeast Texans should be watchful for coastal flooding.

“We’re forecasting tide levels of three to three and a half feet above the normal water level, and this potential for coastal flooding could continue through early Tuesday morning,” Humphrey said. “Our main concern for Southeast Texas is obviously the heavy rainfall, but those coastal waters could cause problems as well.”

Humphrey said Southeast Texas received very little rain Saturday morning and afternoon — just under one-tenth of an inch by 4 p.m. — compared to the Lake Charles region, which received 1.29 inches by the same time.

However, he said, heavier rainfall could make its way into the region Sunday if a small incoming storm does not dissipate when it reaches land.
