The National Hurricane Center and Harris County meteorologist Jeff Lindner now predict that a tropical cyclone will likely develop in the Gulf of Mexico later this week.
Models Now Predict Westward Development
Overnight, the threat increased westward along the Louisiana and Texas coasts.
The National Weather Service expects a trough of low pressure located over central Georgia to move southward toward the northeastern Gulf of Mexico. There, it should form a broader area of low pressure in a couple of days. A tropical depression will likely form by the end of the week while the low meanders near the northern Gulf Coast.
Regardless of development, this system has the potential to produce heavy rainfall along portions of the northern and eastern U.S. Gulf Coast later this week. Formation chance in the next two days remains low at 10 percent, but increases to 80 percent in the 5-day outlook.
Upper air conditions appear favorable for a tropical system to form and then intensify over much of the US Gulf coast and northern Gulf. Models now predict that any Gulf system would tend to track more westward.
“A tropical storm is likely and a hurricane is not out of the question,” says Lindner. “If forecast models continue to show the westward motion and potential threat to the northwest Gulf, significant forecast changes will be required over the next 24-48 hours.”
What to Do Now
- Closely monitor the progress of this system.
- Check hurricane preparation kits and plans.
- Be ready to enact those plans later this week.
- Monitor weather forecasts closely.
