A National Weather Service beach hazards statement warning of rip and longshore currents is set to remain in effect through Thursday evening. Surf of 4 to 6 feet with sets to 7 feet along local beaches during the advisory period may be high enough to break over jetties and sea walls.
Forecasters said the surf would gradually decrease Friday, but strong rip currents may still occur.
“Strong longshore currents moving from south to north at the beaches,'' according to the weather service. “Be aware and be careful if you are heading into the water.''
Swimmers can escape a rip current by swimming parallel to the coast before heading back to shore. The NWS also advised beachgoers to obey posted warning signs, use caution around the water and always swim near a lifeguard.
The big waves and rip currents are expected to die down before a heat wave hits this weekend and sends high temperatures up to 20 degrees above average. A NWS excessive heat watch for inland areas is set to run from Sunday morning until Tuesday evening.
Daily high temperatures are predicted to be in the upper 80s to low 90s at the beaches, in the 90s in the mountains, 100 to 110 degrees in the valleys and high desert, and more than 115 degrees in the low deserts.
“Very hot, and potentially dangerous, conditions are forecast for Sunday through the early part of next week as a strong ridge of high pressure develops over the Southwest,'' according to the weather service. “Monday is expected to be the hottest day.''
Forecasters advised the public to avoid potentially serious heat-related ailments by staying well-hydrated, shunning unnecessary outdoor labor and checking on neighbors and relatives -- especially those with health conditions and who lack air conditioning.
The heat is expected to break toward the middle of next week, according to the NWS.
