Last day of summer brings heat advisory to inland areas

Weather

SAN DIEGO — A heat advisory goes into effect Tuesday morning for areas of San Diego County.

The heat advisory begins at 10 a.m. for eastern portions of the county’s valleys, including Escondido, El Cajon, San Marcos, La Mesa, Santee and Poway.

The National Weather Service says highs will reach well into the 90s over the inland valleys and high desert, with 100-105 degree temperatures felt across the Inland Empire and 107 degrees over the lower deserts.

The heat advisory is set to expire at 8 p.m. Wednesday.

Practice heat safety by limiting time outdoors, drinking plenty of beverages to stay hydrated and check on the elderly and those who don’t have air conditioning.

The NWS says the development of a weak low pressure system centered near Southern California and northern Baja will bring a gradual cooling trend Thursday through the weekend.
