Aug. 22 (UPI) -- As much as 6 inches of rain is expected in south Texas, with as much as 10 inches forecast for Mexico, as Tropical Storm Harold hits the region.

Harold made landfall early Tuesday on Padre Island off the coast of Texas. After Emily dissolved late Monday, there are four other storms brewing in the Atlantic, putting an end to what's so far been a quiet hurricane season.

In a final advisory on Tuesday, National Hurricane Center forecasters said heavy rainfall continues to be expected across wide areas of South Texas through Wednesday. Flash-flooding in parts of Mexico's Coahuila and northern Nuevo Leon could lead to possible landslides in mountain regions, they added.

Parts of south Texas can expect to see as much as 6 inches of rain by Wednesday, while parts of Mexico could get closer to 10 inches of rain.

That comes as what's left of the Pacific storm system Hilary moved east toward Nevada.

President Joe Biden said Tuesday his administration is monitoring the remains of the storm system and responding with aid.

"I continue to be briefed on Tropical Storm Harold and its potential impacts on South Texas," Biden said in a statement released from the White House. "At my direction, FEMA pre-deployed personnel to Texas to assist state and local officials and to coordinate on any requests for resources should federal assistance be required. FEMA has also made preparations to surge personnel and resources, if needed."

Biden said he also had been briefed on Tropical Storm Franklin and had directed FEMA to pre-deploy personnel and resources to Puerto Rico and the U.S. Virgin Islands.

Apart from Harold's heavy rains and sustained winds of about 50 mph, the National Hurricane Center warned of "life-threatening" surf and tidal conditions along the shore of the Gulf of Mexico.

Harold was moving north, northwest at around 20 mph and tropical storm warnings were watches are in effect for much of the region.

"Interests elsewhere in eastern Texas and northern Mexico should monitor the progress of this system," the forecast read.

The storm comes with something of a silver lining as temperatures are expected to fall toward 90 degrees Fahrenheit. Highs topping 105 degrees are expected by Thursday, however.

Harold is expected to weaken as it moves further inland.

None of the remaining storms in the Atlantic are expected to pose a serious threat to the U.S. mainland.
