CORPUS CHRISTI, Texas — A downgraded Hanna continued weakening on Monday, July 27, but its remnants still threatened to bring rainfall and flash flooding to waterlogged parts of South Texas and Northern Mexico that have been dealing with a surge in coronavirus cases.

Now a tropical depression, Hanna was 65 miles north of Fresnillo in the Mexican state of Zacatecas as its winds weakened to about 25 mph, the National Hurricane Center said July 27.

Initial reports indicated Hanna dumped up to 15 inches of rain in some areas in South Texas. Another 1 to 2 inches could fall in areas of South Texas that are already water-logged. The northern Mexican states of Coahuila, Nuevo Leon and Tamaulipas could see an additional 4 to 8 inches of rain, possibly producing mudslides in these areas.

Border communities whose health care systems were already strained by COVID-19 cases — with some patients being airlifted to larger cities — continued grappling with Hanna. There were no immediate reports of any deaths on either side of the border.

In the Pacific Ocean, meanwhile, Hawaii avoided a direct hit July 27 from Hurricane Douglas as the storm was moving away from the main Hawaiian islands.
