Heat Wave Prompts Heat Advisory For Escondido

ESCONDIDO, CA — A heat wave was expected to bring hot weather to San Diego County Thursday and into the weekend.

The high temperatures prompted a heat advisory for the valleys, including the cities of El Cajon, Escondido, La Mesa, Poway, San Marcos and Santee. The advisory was in effect from noon Thursday until 7 p.m. Friday, according to the National Weather Service.

A strong high pressure and offshore flow were expected to send temperatures between 90 to 100 degrees in the valleys, forecasters said.

"High temperatures may cause heat illnesses to occur, especially with physical exertion during the afternoons," weather officials said.

The NWS predicted the weather Thursday to be mostly sunny with high temperatures from 79 to 84 degrees along the coast. The inland areas were expected to be mostly sunny with highs from 88 to 92, while the mountains were expected to be sunny with highs from 79 to 88. The deserts were predicted to be sunny with highs from 95 to 98.

Forecasters advised people to drink plenty of fluids, stay in air-conditioned rooms, stay out of the sun, and check on relatives and neighbors. Weather officials also reminded residents that young children and pets should never be left unattended in vehicles.
