Monday is likely to bring slightly cooler temperatures to the west of the mountains, but the worst heat is yet to come for the mountains and deserts on Tuesday, according to NBC 7 meteorologist Dagmar Midcap.
The NWS extended the excessive heat warning through 8 p.m. Wednesday for all areas. It said it appears that any significant cooling will be delayed until Friday.
Elevated rip currents are likely at beaches, but otherwise calm conditions on the coast, Midcap said.
