5-Day Outlook

A tropical wave over the northwestern Caribbean Sea is producing disorganized showers and thunderstorms this morning. This disturbance is forecast to move west-northwestward and cross the Yucatan Peninsula later today with no significant increase in organization. Some development of this system is possible after it emerges across the southwestern Gulf beginning on Thursday. Regardless of development, locally heavy rainfall, increased rip currents, and increased swells will be the likely impacts for South Texas beginning later this week. We will continue to provide updates as conditions warrant so be sure to monitor the forecast over the next couple of days.

Tropical Storm Erin is currently located over the eastern Atlantic and will continue moving quickly westward. The storm is forecast to become a hurricane later this week in the central Atlantic. Erin could approach the northern Leeward Islands, Virgin Islands, and Puerto Rico this weekend, though potential impacts remain uncertain. There is even greater uncertainty for the Greater Antilles, Bahamas, U.S. East Coast, and Bermuda next week. Now is a good time to review hurricane preparedness plans.

Today will be hot with heat indices from 105-110. Please remember to practice heat safety: take breaks, drink water, and look before you lock. A low chance (20-30%) of showers is possible across the coast and the Victoria Crossroads this afternoon.

Expect sunny skies with a low chance of storms today across area beaches with highs in the upper 80s. Winds will be around 10 mph from the south. There is a LOW risk of rip currents today. Remember, low risk doesn't mean no risk and caution should still be used if entering the water.

Mostly clear skies tonight with lows in the mid-70s to around 80 across the area. Light southeast winds.

The region will remain between two ridges, supporting daily isolated showers and thunderstorms driven by the sea breeze, with highs in the 90s to 105s and heat indices near 110 degrees, creating moderate to major heat stress. Some heat relief is possible this weekend with forecasted rain and cloud cover. The National Hurricane Center has introduced a 20% chance of tropical development in the northwestern Caribbean over the next seven days, with the system expected to enter the southwestern Gulf by Thursday and move inland this weekend. Regardless of development, South Texas could see locally heavy rainfall, increased rip currents, higher swells, and possible coastal flooding.
