Houston Faces Triple-Digit Heat Index as Saharan Dust Plume Blankets Skies, Weather Officials Say

Southeast Texas residents are being urged to brace for another punishing stretch of heat as a fresh wave of Saharan dust settles over the region, pushing heat index readings as high as 108 degrees, according to the National Weather Service.

Need to Know

Afternoon temperatures expected to climb into the mid-to-upper 90s
Heat index could feel like 100 to 108 degrees in parts of Houston
Storm activity remains limited today, mostly confined near the coastline
Rain coverage expected to expand starting Friday and hold through early next week
A layer of Saharan dust is lingering today before thinning by the weekend
A second, denser dust plume may move in as early as Tuesday
Federal forecasters confirm no tropical storm formation is expected across the Atlantic in the coming week

Heat Grips Houston Once Again

The city is bracing for another round of oppressive summer heat, with highs expected to reach the upper 90s this afternoon. Officials caution that the combination of humidity and sunshine will make it feel considerably hotter, with the heat index projected to hit as high as 108 degrees in some neighborhoods.

Storm Chances Dip Before Rebounding

Unlike the widespread storms seen earlier in the week, todays rain activity is expected to stay limited, with only isolated coastal showers likely — mostly along and south of the I-10 corridor. Inland areas are expected to remain largely dry.

That trend, however, won’t last. Forecasters say a return of deeper Gulf moisture will fuel a noticeable jump in storm coverage by Friday, with wetter conditions expected to persist into the weekend and early next week.

Saharan Dust Creates Hazy Skies, Air Quality Concerns

A layer of Saharan dust continues to hang over the Houston region, giving the sky a hazy look and setting up the potential for a striking orange-red sunset this evening. The plume is expected to thin out overnight and remain lighter through the weekend — though a second, thicker wave of dust could roll back in as early as Tuesday, coinciding with a dip in rain chances.

Due to the dust, air quality is expected to sit at a moderate level today. Health officials recommend that individuals with asthma, allergies, or other respiratory conditions limit prolonged outdoor exposure.

Tropics Remain Calm — For Now

According to federal weather monitoring agencies, the Atlantic basin remains free of any tropical development risk over the next seven days. Meanwhile, forecasters are keeping an eye on a few disturbances in the Pacific — one expected to track well south of Hawaii, and others forming over open waters south of Mexico, though none currently pose a direct threat.

Hurricane Season Outlook Downgraded Again

Storm researchers at a leading university-based hurricane center have once again lowered their outlook for the 2026 Atlantic hurricane season, now projecting activity to fall well below historical averages.

The revised forecast calls for:

9 named storms
4 hurricanes
1 major hurricane

Meteorologists attribute the reduced activity to a strengthening El Niño pattern. Despite the calmer outlook, experts continue to stress that residents should not let their guard down — as it only takes a single landfalling storm to turn an otherwise quiet season into a destructive one.
