SAN DIEGO - The San Diego County coastline is in for more strong rip currents and elevated surf Thursday, but forecasters said the potentially dangerous ocean conditions would begin to calm before a heat wave sends temperatures soaring this weekend.
A National Weather Service beach hazards statement warning of rip and longshore currents is set to expire this evening, but strong rip currents may still occur after the waves lower. Swimmers can escape a rip current by swimming parallel to the coast before heading back to shore.
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.
The big waves are expected to die down before a heat wave hits this weekend and sends high temperatures up into potentially record-breaking territory. A NWS excessive heat watch for inland areas is set to run from Sunday morning until Tuesday evening.
"The main message of our excessive heat watch is to get ready for the heat particularly away from the coast Sunday through Tuesday," according to the weather service. "Temperatures will exceed 100 in most valleys and all deserts, even exceeding 115 in the lower deserts."
Daily high temperatures are predicted to range from 90 to 96 degrees in the mountains to 95 to 100 degrees in the valleys to 110 to 120 degrees in the deserts. Forecasters said Monday -- the first day of summer -- will likely be the hottest day.
Forecasters advised the public to avoid potentially serious heat-related ailments by staying well-hydrated, avoiding 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.
