80% chance of tropical storm forming in US Gulf this week
National Hurricane Center puts 80% odds on tropical depression forming in the central or southern Gulf within the next week.
A trough of low pressure in the southwestern Gulf is producing disorganized thunderstorms over warm waters that favour development. Forecasters rate an 80% chance that a tropical depression or named storm will form within the next week.
If winds reach 39 mph, the system will be named Isaias on the 2026 Atlantic hurricane list. Heavy rainfall not connected to the possible tropical system is already causing flash floods across the Gulf Coast.
The system is expected to drift east then turn north toward the coast. Interests from Florida's Panhandle to Louisiana should monitor progress for potential storm surge and wind impacts.
More heavy rain is forecast across the region by week's end regardless of storm development.
