Tropical Storm Alberto Approaches Houston
Tropical Storm Alberto, the first named storm of the Atlantic hurricane season, has formed in the southwestern Gulf of Mexico and is making its way towards the Texas coast. Houstonians should prepare for a significant rainfall event, strong winds, and coastal flooding as the system makes landfall south of our region, bringing widespread impacts across Southeast Texas.
Understanding Tropical Storm Alberto
Alberto developed from a broad area of low pressure in the Bay of Campeche, becoming a tropical storm with sustained winds. While it is not expected to rapidly intensify into a hurricane, its large size means its impacts will be felt far from its center. The primary concern for the Greater Houston area is not necessarily direct wind damage, but rather the extensive moisture it will pull from the Gulf, leading to heavy, prolonged rainfall and significant coastal hazards.
Expected Impacts for Greater Houston
Heavy Rainfall and Flooding Risk
The most significant threat from Tropical Storm Alberto for Houston and its surrounding communities is the potential for heavy rainfall. Forecasts indicate several inches of rain could fall across the region over multiple days, with isolated higher amounts possible. This saturation significantly increases the risk of street flooding, especially in low-lying areas and neighborhoods with poor drainage. Bayous and creeks, already prone to overflow during intense rain, will need close monitoring. Driving conditions are expected to deteriorate rapidly during periods of heavy downpours, making travel hazardous.
Coastal Flooding and Dangerous Conditions
Coastal areas, including Galveston Island, the Bolivar Peninsula, and communities along Galveston Bay, face a heightened risk of coastal flooding and elevated tides. A storm surge, combined with strong onshore winds, will likely inundate low-lying coastal roads and properties. Dangerous rip currents will make swimming extremely unsafe, and hazardous boating conditions are anticipated in the Gulf and bay waters. Residents in these areas should pay close attention to local advisories and be prepared to take action if evacuations are recommended.
Wind Gusts and Potential Power Outages
While Alberto’s strongest winds are concentrated near its center, the Houston metropolitan area can still expect breezy to gusty conditions. Sustained tropical storm force winds are less likely inland, but gusts could reach 30-45 mph, particularly closer to the coast. These winds are strong enough to cause scattered power outages, down small tree branches, and make driving high-profile vehicles challenging. Secure any outdoor loose items that could become projectiles in strong winds.
Regional Impact Overview
The severity of impacts from Tropical Storm Alberto will vary across Southeast Texas. Here’s a brief comparison:
| Category | Coastal Areas (e.g., Galveston, Surfside) | Inland Areas (e.g., Central Houston, Katy) |
|---|---|---|
| Rainfall | Heavy, potential for 4-8 inches, locally higher. | Heavy, potential for 3-6 inches, locally higher. |
| Wind | Sustained tropical storm force possible, gusts up to 45 mph. | Gusts up to 35 mph, breezy conditions. |
| Flooding Risk | High risk of coastal flooding from storm surge and high tides; street flooding. | Moderate to high risk of street flooding, bayou overflow. |
| Other Hazards | Dangerous rip currents, hazardous marine conditions. | Isolated power outages, challenging driving. |
Storm Timeline and What to Watch Next
The impacts from Tropical Storm Alberto are expected to begin intensifying late Wednesday night and continue through Thursday. The peak of rainfall and wind activity is likely to occur during Thursday. While the storm is forecast to move inland and weaken, residual moisture could continue to bring showers into Friday. Houstonians should remain vigilant even after the storm’s immediate passage, as saturated grounds and elevated waterways will take time to recede. Continue to monitor official forecasts from the National Weather Service Houston/Galveston office and local emergency management for the latest updates on the storm’s path and local impacts.
Frequently Asked Questions
- When will the worst of the storm hit Houston?
The most significant impacts, including heavy rain and stronger winds, are generally expected from late Wednesday night through Thursday, peaking throughout Thursday. - Should I prepare for power outages?
Yes, scattered power outages are possible due to gusty winds and heavy rain. It’s wise to have flashlights, extra batteries, and fully charged mobile devices ready. - Is it safe to travel during the storm?
Travel is discouraged during periods of heavy rainfall and strong winds due to reduced visibility, road closures from flooding, and hazardous driving conditions. If you must travel, check road conditions beforehand. - What’s the difference between a tropical storm and a hurricane?
A tropical storm has sustained winds between 39 and 73 mph. If sustained winds reach 74 mph or higher, it is upgraded to a hurricane. Alberto is currently a tropical storm. - Where can I get official updates?
Rely on official sources such as the National Weather Service Houston/Galveston (weather.gov/houston), local news outlets like ABC13, and city/county emergency management agencies.
As Tropical Storm Alberto approaches, prioritize your safety and that of your family. Stay informed through official channels, secure your property, and have a plan in place. Remember, turn around, don’t drown.
