You’d think it was perfect beach weather, but you should think twice before getting in the Gulf today.

The National Weather Service in Mobile is warning beachgoers in Alabama to beware of rip currents and has raised the rip current risk for the rest of Saturday from moderate to high — the most serious category.

A high rip current risk means that the water is dangerous for everyone, no matter how good of a swimmer you are. A high risk also means that rip currents are “likely.”

The rip current risk for northwest Florida is moderate, which means rip currents are possible.

Rip currents are the biggest weather-related killer — more than tornadoes, hurricanes, flooding and lightning combined — for the forecast area covered by the weather service in Mobile (which includes parts of southeast Mississippi and the northwest Florida Panhandle).

The weather service said conditions today have become more favorable for rip currents — which is particularly bad timing considering it’s a busy beach weekend.

The weather service said lifeguards have reported strong rip currents along Alabama beaches this afternoon and elevated surf conditions.

Tips for dealing with rip currents from the weather service: “Swim near a lifeguard. If caught in a rip current, relax and float. Don’t swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.”

Don’t despair, beachgoers. The weather service currently has a low rip current risk to begin on Sunday and last through at least Tuesday night.
