Dangerous Heat Grips San Diego for 2nd Day

A heat warning is issued when dangerous heat is expected. Prolonged hot temperatures could lead to heat illness and, in some cases, heat stroke.

San Diegans dealt with dangerous heat for the second straight day as a heatwave gripped the region Thursday.

The National Weather Service issued an excessive heat warning for the deserts and a heat advisory for inland valleys through 9 p.m. Thursday due to soaring temperatures.

NBC 7 Meteorologist Brooke Landau said in some inland valley areas were still experiencing 96 to 98-degree heat at 4 p.m.

Thursday's heat marked the end of the heat wave, but another one is on its way quickly, according to Landau.

Landau said there's been high pressure aloft that brings along atmospheric compression which dries out the air and boosts temperatures. The NWS said fire danger on Friday would be minor, and Landau said wind speeds the heat advisorya reas would be calm.

A low pressure system heading our way from the Pacific Northwest will bring the region a reprieve from the heat, but only for a couple of days.

Another heat wave is expected to hit San Diego County next week, according to NBC 7 Meteorologist Sheena Parveen. 

A heat warning is issued when dangerous heat is expected. Prolonged hot temperatures could lead to heat illness and, in some cases, heat stroke. 

The temperatures in the deserts and inland valleys were considered dangerous because little relief was expected overnight.

NBC 7 Meteorologist Sheena Parveen said people should stay in air-conditioned rooms, stay out of the sun, check on relatives and neighbors and never leave pets or children in cars. 

San Diego County provides dozens of "cool zones" where residents can get out of the sun and into an air-conditioned room. For a list of locations, visit here
