Heat index could hit 114 today in some spots

HARLINGEN — High humidity levels and the usual summer heat will create potentially dangerous heat conditions today.

National Weather Service forecasters have issued an alert that heat index values — the “feels like” temperature — will be between 105 and 110 today up and down the Valley and in the ranchlands.

Isolated spots could see heat indices rising to 111 to 114 degrees.

The alert covers Cameron, Willacy, Hidalgo, Starr, Zapata, Jim Hogg, Brooks and Kenedy counties.

Actual temperatures will range from 98 degrees along the gulf in Brownsville to 104 degrees in McAllen.

Forecasters also warn there will be an elevated risk of rip currents at gulf beaches at South Padre Island and at Boca Chica beginning Wednesday night and continuing through Friday.

Those beach conditions will be caused by Tropical Storm Franklin’s northern cloud bands as the storm approaches the Mexico coast.

Franklin continues to move to the west-northwest at a 14 mph clip.

A west-northwestward to westward motion is expected over the next couple of days as the storm moves across the Yucatan peninsula today, emerging into the Bay of Campeche tonight.

Additional weakening is expected as Franklin moves across the Yucatan peninsula today, but re-strengthening is forecast to begin tonight and Wednesday.

Impacts across the lower Texas coast and lower Rio Grande Valley will range from an increased chance of showers and thunderstorms Thursday into Friday, to elevated rip currents, some minor beach erosion, higher surf and higher seas on the gulf, weather forecasters in Brownsville say.
