Life-threatening storm surge is expected anywhere along the Gulf Coast of Florida. Areas on the east side of the storm and closest to the eye at landfall should anticipate 10-15 ft of inundation. Remember the right front quadrant of the storm as it is approaching land is where the highest surge and strong winds will be. At Cat 3 115 mph sustained winds are anticipated at landfall.

Once in the Gulf, this will send swells rippling toward the Texas Coast, and our rip current risk will increase. Minor coastal flooding will also be possible thanks to the north wind and the longer period of swells.

The most dangerous seas will be in the Eastern Gulf of Mexico with wave heights up to 20 ft. Along the Texas Coast, expect 2-4 ft waves with an 8-11 second period Thursday through Saturday. This will increase the rip current risk and make conditions along the Texas Coast hazardous for swimming. We have Weather Impact Alerts up for this hazard. There may be some minor coastal flooding on Thursday and Friday. too.

2024 Atlantic Hurricane Season Names & Observed Strength

On May 23, NOAA released their forecast for the 2024 Atlantic Hurricane Season. They're predicting an above-average year, with 17-25 named storms. This is the highest pre-season forecast they've ever issued.

The high number of storms forecast is due to near-record sea surface temperatures and the return of La Nina, both of which favor tropical cyclone development. We talk more about those in our Hurricane Special, which you can watch here!
