Houston weather: Heat advisory in effect this weekend

article

HOUSTON - A Heat Advisory is in effect for all of southeast Texas from noon to 7pm on Saturday and Sunday. Highs will reach the upper 90s and low 100s, with heat index values around 106 to 110 degrees.

Hot weekend with little rain

The heat wave continues into the weekend, with highs around 100 degrees or hotter. Most areas stay dry, but a few isolated showers or storms could develop Saturday evening. Highest coverage will be north of I-10.

Tropics mostly quiet

The Atlantic remains unusually quiet for late August, with no organized tropical threat to Texas right now.

A tropical wave is expected to move off the coast of Africa where development may be possible as it moves across the Atlantic. There's a very low chance a brief weak tropical or subtropical system could form in the NE Atlantic over the next few days. But it is headed towards Portugal and Spain and is not a threat to the U.S.

Another area near the island of Bermuda will likely stay away from the east coast of the U.S. We will continue watching the tropical wave train in the eastern Atlantic as activity typically increases heading toward the peak of hurricane season in September.
