Good afternoon partners,
Here are the slides for the 2pm webinar
Main Takeaways:
Main Takeaways:
- There is a medium (40%) chance of tropical cyclone development in the northern Gulf late this week.
- Regardless of development, the system forecast to move through the gulf will bring multiple rounds of heavy rain during the Wed-Sun time frame, with the greatest threat Thursday and Friday.
- High rainfall rates are likely to overwhelm drainage capacity at times, resulting in street flooding and at least a localized flash flooding threat.
- Areas that see the most rain could experience more significant flash flooding, especially if there aren’t sufficient breaks between rounds of heavy rain to allow drainage to catch up.
The slides will also be available shortly on our website here:
