Houston is waking up to a sticky start Sunday, with muggy air and temperatures already around 81°F under partly cloudy skies. By afternoon, the heat is expected to climb into the low 90s, and showers and thunderstorms are likely after 10 a.m. Even if your neighborhood dodges the rain, it will not dodge the heat, with heat-index values pushing into the low to mid 100s. Any stronger storms could bring brief heavy downpours that cause localized street and yard flooding and cut visibility on the roads, so plan extra time for errands and keep water and shade close if you will be outside.
Afternoon Heat And Storms
Rain chances ramp up through the morning and become more widespread in the afternoon, with the best shot at showers and thunderstorms from late morning into the evening. Forecasters put precipitation odds at roughly 60 to 70%, and new rainfall amounts of about a quarter to a half inch are possible Sunday night, with isolated heavier pockets. The bigger soaking is expected Monday into Tuesday, when totals of 1 to 3 inches are possible, with isolated spots seeing 4 to 6 inches. High temperatures will top out in the low 90s, with heat-index values near 103 to 107°F in some areas, so outdoor workers and vulnerable residents are urged to take precautions, according to the National Weather Service Houston/Galveston.
Cooling Centers And Heat Relief
For anyone who needs a break from the heat, the city and partner organizations have opened "Beat the Heat" sites and other air-conditioned spots around Houston this season, with local coverage outlining where to go and when. Residents without air conditioning can call 3-1-1 to locate nearby facilities or ask about assistance. For a full rundown of the city’s program and how to apply for portable units, see coverage of how Houston plans to "Beat the Heat".
Beaches And Rip Currents
If you are heading to the coast to cool off, conditions may not cooperate. Gulf-facing beaches will stay hazardous through Monday morning, with a high risk of rip currents and elevated tides that could lead to minor coastal flooding. Lifeguards and officials urge beachgoers to swim near staffed towers and avoid wading into rough surf, and to obey posted flags. Plan for choppy conditions and check beach reports before you go, as the increased rip-current threat and elevated tides along the coast are being highlighted by forecasters, according to the NWS.
What To Do Today
Stay hydrated, wear light and breathable clothing, and try to schedule heavy outdoor work for the early morning or later evening. Do not drive through standing water, and move to higher ground if heavy rain leads to localized flooding in your area. Keep your phone charged and follow local news or a weather radio for updated watches and warnings. If you are at the beach, stick close to lifeguards and skip the water in flagged or obviously rough conditions.
