Blistering Heat Moving Into San Diego-Area Deserts, Mountains

SAN DIEGO (CNS) - Temperatures will soar into the triple digits in San

Diego-area mountain and desert communities over the coming week, as more

moderate summertime conditions prevail in coastal and inland-valley locales,

forecasters said today.

Maximum thermometer readings in Borrego Springs and other parts of the

arid eastern reaches of the county are expected to climb steadily over the

workweek before topping out as high as 120 degrees by Sunday, according to the

National Weather Service. In the mountains, temperatures could reach 108, the

agency advised.

Due to the potentially hazardous conditions, the agency has issued an

excessive-heat warning, effective through 8 p.m. Monday for desert and mountain

areas.

Not only will daytime temperatures be sweltering over the period in

the hottest spots, but overnight lows will be significantly elevated,

especially in the low deserts, according to the NWS.

Due to the predicted extreme heat, Cedar Creek Falls, Eagle Peak

trails, the San Diego River Gorge and Three Sisters Falls have been closed

until further notice, according to Cleveland National Forest officials.

The NWS advised people in the hottest locations to drink plenty of

fluids, stay out of the midday sun and check up on potentially at-risk

relatives and neighbors over the course of the heat wave.

Additionally, ``young children and pets should never be left

unattended in vehicles under any circumstances,'' the agency advised.

Daytime highs will are excepted to ascend into the 90s in the inland

valleys over the period, while mercury readings along the coast should max out

in the high 70s Wednesday and Thursday and dip down a few degrees by the

weekend, according to meteorologists.
