Tropical Storm Laura strengthened to a hurricane Tuesday morning, reaching maximum sustained winds of 75 mph as it barreled toward the Gulf of Mexico along Texas and Louisiana, bringing the possibility of life-threatening storm surges.
Laura, which is forecast to reach category 3 strength Wednesday, was expected to make landfall late Wednesday or early Thursday near the Texas-Louisiana border as a “major hurricane,” the National Hurricane Center warned Tuesday afternoon.
Hundreds of thousands of people in the two states have been ordered to evacuate.
A storm surge warning was issued from the San Luis Pass strait in Texas to the mouth of the Mississippi River, while a hurricane warning was in effect from the strait to the unincorporated community of Intracoastal City, Louisiana.
Other areas, including Sargent, Texas, were under tropical storm warnings.
The storm, which dumped heavy rain on Cuba, may also threaten Florida, the National Hurricane Center said.
Rain showers could reach the coasts of Texas and Louisiana by Wednesday afternoon, with strong winds arriving later in the day. The storm’s impact is forecast to be felt far away.
A life-threatening storm surge is forecast for a long stretch of the Texas and Louisiana coastlines, with 7 to 11 feet possible. Even Lake Pontchartrain, even though it is forecast to be far from the center of the storm, is forecast to experience 2 to 4 feet of storm surge.
The storm surge, combined with high tide cycles and large destructive waves crashing on shore, will lead to exceptionally dangerous conditions along the coast.
In addition, from Wednesday afternoon into Saturday, Laura is expected to produce rainfall of 4 to 8 inches, locally up to 12 inches, across parts of the west-central Gulf Coast near the Texas and Louisiana borders north into parts of the lower Mississippi Valley. That will lead to widespread flash and urban flooding, as well as minor to moderate river flooding.
Several counties and cities along the coast of Texas issued mandatory evacuation orders beginning Tuesday morning, including the city of Galveston, Orange County and Jefferson County, which has a population of more than 250,000.
Texas A&M University at Galveston tweeted Monday that it was ordering an evacuation.
Galveston Mayor Pro Tem Craig Brown told The Weather Channel: “Today is the day. The weather is still nice here in Galveston. This is the day for everybody to get their belongings together and, for the safety of themselves and their family, to go ahead and evacuate today. Do not wait.”
Mayor Thom Kolupski issued a voluntary evacuation order for Seabrook in Harris County, and he encouraged elderly residents and people with medical conditions to take precautions.
“This notice is very important to elderly residents and/or people with medical conditions. We encourage these residents to evacuate these portions of the city at your convenience, however, due to rain, storm surge and the probability of heavy traffic you are encouraged to do so sooner rather than later,” he wrote in a Facebook post.

The mayor of Grand Isle, a small town in Jefferson Parish, Louisiana, issued a mandatory evacuation order Sunday. Other parts of Jefferson Parish were under voluntary or mandatory evacuation orders, The Weather Channel reported.
Authorities have begun moving prisoners in Louisiana and Texas in preparation for landfall Wednesday evening. The Calcasieu Parish Sheriff’s Office said Tuesday on Facebook that it was preparing to move more than 900 inmates to other facilities in Louisiana.
“The Sheriff’s Office will be increasing manpower on patrol and will do everything we can to keep you and your property safe, but at some point it will be too hazardous for deputies to respond and for that time frame you need to ensure your own personal safety if you choose to stay,” the post said.
About 3,400 offenders will be moved from prisons at risk from the hurricane’s winds and storm surge to other locations in Texas, the state Criminal Justice Department said.
Louisiana Gov. John Bel Edwards said Monday that residents should begin taking precautions, as Laura “is going to be a significant storm.”
Texas Gov. Greg Abbott told reporters Monday that the third anniversary of the devastating Hurricane Harvey is approaching this week. Abbott reminded residents to be aware of the risk of contracting the coronavirus as the state’s positive test results begin to decline following an alarming rise in the number of cases last month.
“Remember, just because a hurricane is coming to Texas does not mean that COVID-19 either has or is going to leave Texas,” Abbott said. “COVID-19 is going to be in Texas throughout the course of the hurricane.”
Abbott recommended hotels and motels as the ideal options for evacuated residents, but officials promised that shelters throughout the state will have personal protective equipment and testing teams.
