Heat wave to subside beginning Tuesday night
SAN DIEGO (CNS) – The National Weather Service issued a heat advisory Tuesday for San Diego County amid triple-digit temperatures inland, while moisture associated with Hurricane Odile pumps up the relative humidity across the region.
The advisory also covers normally cool coastal areas, where highs are forecast to range from 86-93 degrees. Highs a few miles inland are forecast to be 95-100 degrees a few miles inland, and 100-plus in the valleys and deserts.
On Monday, a record high of 103 degrees was set for the date in Ramona — two degrees hotter than the old record set in 2012, according to the National Weather Service. In Alpine, a 30-year-old record of 102 degrees was tied.
“Abnormally hot temperatures can be stressful to animals and humans, making it hard for the body to acclimate and remain hydrated,” according to the NWS. “Without precautions even healthy adults could experience heat stress and illness.”
Many area schools without adequate air conditioning shortened their schedules.
About 120 San Diego Unified School District campuses without full air conditioning have minimum-day schedules today, including Clairemont, Crawford, Garfield, La Jolla, Madison, Mira Mesa, Mission Bay, Morse and University City high schools. After-school physical activities were canceled at all city schools.
A full list of schools on a reduced schedule today is available on the district’s website, sandi.net.
Sweetwater Union High School District officials have implemented a minimum schedule at Mar Vista Academy, Castle Park and Hilltop middle schools, and Chula Vista, Mar Vista and Sweetwater high schools.
The Coronado and National school districts also shortened their school days.
Those trying to beat the heat can head to more than 100 air conditioned buildings, such as libraries and recreation centers — dubbed “Cool Zones.” A list of county Cool Zones is available at CoolZones.org. or by calling 211.
Forecasters urged people to schedule outdoor activities for the cool of the morning or in evening, to take frequent breaks in shady or air-conditioned areas and to know the signs of heat exhaustion and heat stroke. Those planning to be outside were advised to wear light, loose clothing and to drink plenty of water.
Forecasters said that temperatures would begin to cool Wednesday, though higher than average humidity, thanks to remnants of Odile.
