Map showing the Rip Current Risk, today (October 2) across the southeast and eastern U.S. The map shows Moderate to High Risk of rip currents from Florida to Maine.

Rip Currents: Know Your Options. Rip currents are powerful currents of water moving away from shore. They can sweep even the strongest swimmer away from shore. If at all possible, swim near a lifeguard. If caught in a rip current: 1) Relax, rip currents don't pull you under. 2) Don't swim against the current. 3) Swim out of the current, then to shore. 4) If you can't escape, float or tread water. 5) If you need help, yell or wave for assistance. The image shows a rip current as a narrow flow of water moving in a line directly away from the beach, with waves on either side moving in the opposite direction towards the beach. Arrows point away from either side of the current and into the waves, parallel to the beach, indicating the path of escape from the rip current.

Heading out to the beach today? ⛱️

Use extra caution given the Moderate to High rip current risk from Florida to Maine today (October 2). Try to find a beach with lifeguards - and when in doubt, don't go out!

Swells and high surf from Imelda are expected to produce dangerous marine conditions and rip currents along much of the East Coast of the United States during the next several days.

Ocean waves are shown breaking offshore with text: Caught in a Rip Current? Here’s How to Survive. Relax, stay calm and float to conserve energy; Swim out of the current by following the shoreline or breaking waves, then at an angle toward the beach; Avoid swimming directly against the current; If you can’t reach shore, yell or wave for help.

Designate a water watcher who can call 9-1-1
Adhere to all posted signs
Keep children within arms reach
Only enter the water if you can swim safely
Take a flotation device with a leash
"When in doubt, don't go

Swimming without a lifeguard increases your chance of drowning, but not all beaches have lifeguards. If you’re visiting a beach without a lifeguard, follow these tips to swim safely, and remember, when in doubt, don’t go out. weather.gov/beach πŸ–οΈ

Spoke with the Times today about rip current safety. We have already had at least 36 surf zone drownings in the US this year. Please stay safe on your next trip to the beach.

Yes - saltwater intrusion is a concern for sure, and can potentially seep into drinking water for instance, and also a concern for building foundations - (e.g. the condo collapse from several years ago)

Sad to see that leadership didn’t approve of my suggested post language (assuming since this is what is posted) that I submitted on my last day in May as the social media manager.

NOAA is hemorrhaging personnel, NWS offices are short-staffed by as much as 60%, workers are living in fear of losing their jobs, afraid of political retribution for speaking out, and they think gaslighting the entire weather community is an effective PR strategy? There is no joy in Mudville.

Finally finished Fellowship! Immediately after it was over they asked if we could start Two Towers, so I guess it was a hit so far. The only spot that was a little tough for my 8 year old was Boromir. They were all mad it was such a cliffhanger, but that’s good! Will keep this thread going.
