Temperatures will decline slightly in L.A. County Thursday but remain in the low 100s in the Antelope Valley as the Southland’s heat wave enters its fourth day.
An excessive heat warning remains in effect until 7 Thursday evening in the Antelope Valley, where temperatures are again forecast to be around 20 degrees higher than normal.
Thursday’s conditions will be much as they’ve been this week, with the National Weather Service again forecasting highs of 75-99 along the coast, 90-100 in most valley areas, 95-105 in the Antelope Valley, and 80-100 in the mountains and foothills.
“Dangerously hot conditions with temperatures of 100 to 105 degrees is expected,” the NWS again warned Thursday in discussing the Antelope valley. “Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities.”
The weather service urged residents to “drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.
“Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heatstroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 911.”
