Rip Current StatementModerate · Expected · Likely

25 0657Z to 27 2200Z

San Juan and Vicinity; Northeast; North Central; Northwest; Mayaguez and Vicinity; Culebra

* WHAT...Life-threatening rip currents. * WHERE...Beaches along the northwest to northeast coast of Puerto Rico and Culebra. * WHEN...Through Tuesday afternoon. * IMPACTS...Rip currents can sweep even the best swimmers away from shore into deeper water, where it becomes difficult to return to safety.

There is a high risk of rip currents. Rip currents are powerful channels of water flowing quickly away from shore, which occur most often at low spots or breaks in the sandbar and in the vicinity of structures such as groins, jetties and piers. Heed the advice of lifeguards, beach patrol flags and signs. If you become caught in a rip current, yell for help. Remain calm, do not exhaust yourself and stay afloat while waiting for help. If you have to swim out of a rip current, swim parallel to shore and back toward the beach when possible. Do not attempt to swim directly against a rip current as you will tire quickly.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.

FORECAST & PILOT NOTES · SUPPLEMENTAL

Extended forecast and pilot notes

Current aviation conditions show flight category VFR, wind from 120° at 3 kt, visibility 10 SM, ceiling none. Forecast suggests sunday scattered rain showers, high near 90F, low near 80F, 40% chance of precipitation. Key risks: thunderstorms in the forecast. Note: the NWS forecast for now reads "Isolated Rain Showers" but the current METAR shows none of it; the observation and forecast differ, so trust the METAR for current conditions.
