Monitoring a Weak Gulf Disturbance

We’re keeping an eye on a broad area of low pressure currently over Florida. As it moves into the northern Gulf over the next day or so, it will have a brief window for possible development heading into the end of the workweek and the start of the weekend.The National Hurricane Center is giving it a low 10% chance of formation within the yellow-shaded area on their outlook.

One of the main limiting factors is moderate wind shear, which is expected to persist in that region over the next few days.

If development were to occur, the system would take the name Dexter and would likely track away from Florida.

Regardless of development, this disturbance will continue drawing deep tropical moisture over the state, boosting rain chances.

As it shifts westward this weekend, it will also help pull in drier air behind it. This gives many of us a much-needed break from the rain and a better chance to enjoy some sunshine.

Development odds increase for Invest 93L

The area we’ve been watching off Florida’s east coast, now Invest 93L, has a better chance for development.

The National Hurricane Center is giving it a 40% chance to form in the next 2 days along with a 40% chance within the next 7 days.

The system remains rather disorganized and lopsided but the environment will allow for additional strengthening. Once the system is in the Gulf, it has a better chance to become a tropical depression.

Invest 93L will move west over Florida today and is expected to reach the northeastern Gulf by Wednesday. From there, it eyes the coast of Louisiana / Mississippi. Rounds of heavy rain and flash flooding will be the main concern through this week.

A more northerly track would generally keep the system weaker as it spins closer to land. If it takes a more southerly track, it would have more time over warm Gulf waters to strengthen.

Dexter is the next name in line if this area is able to strengthen. Once winds reach 38mph, it will be a Tropical Depression. Tropical Storm strength is met once the sustained winds are 39mph.

This will mainly be a rainmaker for Florida as deep tropical moisture continues to move over the state as the low moves overhead. Scattered thunderstorms, tropical downpours and flash flooding will be the main impacts, primarily through Wednesday.

We’ll get back to more typical summer thunderstorm coverage at the end of this week – this weekend as the system moves away from Florida.
