SAN DIEGO -- Hot weather in San Diego County is expected to peak Tuesday, but more seasonable conditions should return by the weekend.

A National Weather Service heat advisory for the deserts and mountain areas higher than 6,000 feet is set to expire at 8 p.m. Wednesday.

In the forecast for Tuesday were highs of 75 to 80 degrees at the beaches, 85 to 90 degrees in inland coastal areas, 88 to 93 degrees in the western valleys, 94 to 99 degrees near the foothills, 94 to 100 degrees in the mountains and 109 to 114 degrees in the deserts.

Forecasters said high pressure aloft would “make for very hot afternoons in the mountains, deserts and Inland Empire through Wednesday.'' But temperatures are expected to lower Wednesday into next weekend.

Residents were advised to avoid potentially serious heat-related ailments by staying well-hydrated, avoiding unnecessary outdoor labor and checking on neighbors and relatives -- especially those with health conditions and who lack air conditioning.

Authorities also warned against leaving children or pets in parked cars, which can quickly become death traps in high heat.

To avoid heat-related problems, authorities recommend:

-- engaging in strenuous activities in the early morning or evening hours;

-- staying in an air-conditioned area during the hottest hours of the day;

-- wearing light, loose-fitting clothing;

-- drinking plenty of water while avoiding alcohol and sugary drinks;

-- taking cool showers;

-- never leaving a child, elderly person or pet unattended in a car;

-- shunning unnecessary strenuous work or other activities outdoors during the hottest part of the day;

-- avoiding unnecessary sun exposure, and wearing a wide-brim hat if venturing into unshaded areas;

-- checking on the well-being of elderly relatives and neighbors; and

-- refraining from turning on ovens.

An extremely elevated body temperature -- 103 degrees or higher -- along with dizziness, nausea, confusion and headache are signs of heat stroke or heat exhaustion. Anyone who displays such symptoms should be moved to a shady spot immediately and fanned, sprayed with water or placed in a cool shower if alert, according to the health agency.

A friend or family member also should monitor the stricken person's temperature and keep him or her from consuming any liquids until the condition passes or medical attention is sought, according to health officials.
