TAMPA, Fla. – A tropical disturbance developing in the Southwest Gulf could rapidly strengthen before encountering severe wind shear near the Northern Gulf Coast.

Gulf tropical system development

What we know:

A tropical disturbance known as Invest 92L is rapidly organizing in the Southwest Gulf.

Computer models indicate the system has a high probability of developing into Tropical Storm Isaias in the short term due to warm ocean temperatures.

However, strong wind shear across the northern Gulf is expected to tear the storm apart as it approaches the coastline.

What we don’t know:

Forecasters cannot pinpoint the exact peak strength of the system before it reaches land.

While some computer models bring the disturbance to hurricane status during its brief window in warm waters, it remains uncertain how quickly wind shear will weaken the storm prior to landfall.
