Atlantic hurricane season activity is building again along the Gulf Coast as communities from Florida to Texas monitor a slow-moving storm system. That focus shifted Monday night to Tropical Storm Bertha, which formed in the Gulf of Mexico and is forecast to move generally west toward Louisiana and southeast Texas. Federal forecasters say the storm is not expected to intensify rapidly, but its slow movement could prolong rainfall, coastal flooding and gusty conditions for parts of the region.
Bertha becomes a named storm as forecasters outline a westward Gulf track
Tropical Storm Bertha formed Monday, July 20, after Hurricane Hunter aircraft found stronger winds in a system that had been tracked as Tropical Depression Two, according to the National Hurricane Center. The center said Bertha had maximum sustained winds of 40 mph Monday evening, making it the second named storm of the 2026 Atlantic season. By early Tuesday, local National Weather Service updates for southeast Texas said Bertha had strengthened to 50 mph while drifting in the eastern Gulf.
The storm developed south of the Florida Panhandle and has been moving slowly, a factor that can increase rainfall totals even in places far from the center. The National Hurricane Center said Bertha was expected to move near or along the northern Gulf Coast during the next several days. Forecasts carried the system toward Louisiana by Wednesday and toward the upper Texas coast later in the week.
Forecasters also expanded alerts as the system organized. National Hurricane Center advisories Monday night showed tropical storm watches and then warnings posted for parts of the northern Gulf Coast, with hazardous conditions possible well before any eventual landfall point is known. Associated Press reporting, citing hurricane center forecasts, said storm surge of up to 4 feet was possible in portions of Louisiana, Alabama and Florida, alongside damaging gusts and heavy rain.
For Louisiana, the clearest near-term concern is a combination of rain bands, coastal water rise and tropical-storm-force gusts, especially across the southeastern part of the state. Forecasts cited by ABC News and local Gulf Coast outlets said Bertha could be near or south of New Orleans by Wednesday. National Weather Service local statements also indicated interests in central Louisiana should continue monitoring the storm as conditions evolve.
In Texas, forecasts have pointed to possible impacts spreading into southeast parts of the state from Wednesday into Thursday, with conditions potentially extending toward the upper Texas coast. The National Weather Service office serving Houston and Galveston said early Tuesday that Bertha’s approach could be limited by wind shear, dry air and interaction with Louisiana, but the system could still bring tropical impacts into southeast Texas. Houston-area coverage from ABC13 reported that storm surge of 2 to 4 feet was possible along parts of the upper Texas and Louisiana coast.
What remains uncertain is the exact track, timing and point of closest approach. The National Hurricane Center forecast cone shows a broad area of possible center locations, and the agency had not confirmed a final Louisiana or Texas landfall point as of the latest overnight updates. That means local effects could shift east or west with each advisory, even if the broader threat to Louisiana and Texas remains in place.
Forecasters have tied Bertha’s risk primarily to its slow speed, deep Gulf moisture and a structure that may keep weather spread unevenly across a wide area. The National Hurricane Center said Bertha was expected to strengthen only gradually before weakening later in the week, with dry air, wind shear and land interaction acting as limiting factors. Even so, tropical systems of modest strength can still produce significant flooding rain and coastal impacts.
ABC News reported widespread rainfall totals of 2 to 4 inches along parts of the Gulf Coast through Friday, with isolated amounts up to 8 inches possible. The Associated Press also reported that isolated tornadoes could develop over parts of the central Gulf Coast as outer bands move onshore. Those threats often depend less on a storm becoming stronger and more on how long feeder bands persist over the same areas.
For residents in Louisiana and Texas, the practical expectation is a period of unsettled weather that may begin before the center arrives and continue after it passes. Local officials and weather offices have not released a single comprehensive list of all affected communities because the storm’s path is still subject to change. What is confirmed is that Bertha is now a named tropical storm, and federal and local forecasters expect parts of Louisiana and southeast Texas to remain in its potential impact zone through midweek and possibly into Friday.
