The tropical disturbance in the Gulf of Mexico is still struggling to get its act together. Regardless of what happens to it, heavy rain and flooding are likely for Friday and Saturday.

Tropical development

The tropical disturbance in the Gulf that we’ve been watching for days is still not getting organized and it’s running out of time. The disturbance will be moving inland on Friday, at which point development will no longer be a concern. It is more likely that it just remains a tropical wave like what it has been for the last few days. In the unlikely event that it forms into a depression, the only additional impact would be some breezier conditions.

The Hurricane Hunters flew into the disturbance on Thursday and did not find a closed circulation, indicating that development had not yet occurred. Another plane will fly in on Friday to investigate, if necessary.

It doesn’t matter if it develops or not though because the main impact will remain the same—heavy rain and flooding.

The rain is expected to pick up on Friday and last through Saturday with occasional breaks. There are likely to be some very heavy pockets of rain that will lead to flooding, but determining where those pockets set up is not possible. It will just be important to remember that everyone will be under the threat of heavy rainfall and flooding is likely due to the saturated ground. Any additional rain will lead to flooding. This is why a Flash Flood Watch is in effect through Saturday night.
