Tracking the tropics: All eyes are turning back to the Gulf as Sally weakens

Tropical Outlook

HOUSTON – Sally is no longer a hurricane but it continues to hit the Carolinas, and eventually Virginia, with nasty weather. Rain still poses a big threat to areas in the storm’s path. Four to 8 inches of rainfall are expected in a swath from north Georgia through Virginia. Rain falling over some mountainous terrain could increase the flash flood threat.

The remnants of Sally will pass into the Atlantic Ocean by the weekend and pose no additional threat to the United States.

Expected Rain

Closer to home, we turn our attention to the western Gulf of Mexico for the next area of disturbed weather that could develop into an organized tropical system.

Invest 90-L, simmering in the western Bay of Campeche just off the Mexican coast, will hover for the next several days and produce widespread unsettled weather over the Gulf. A tropical depression or storm is likely by Thursday night. As a new system is brewing, a cold front is expected to drop through Houston by this weekend. High pressure behind this front will help keep invest 90-L south of Houston with the system meandering in the Gulf through early next week.

There is much uncertainty to the forecast for invest 90-L, and it is important to watch the forecast closely as rain chances could be going up next week depending on what happens with invest 90-L.
