Heat Forecast

High pressure over the Four Corners area of the western United States is expected to cause temperatures to soar above 115 degrees Fahrenheit in parts of San Diego County Thursday.

A National Weather Service heat advisory is set to take effect in the mountains and deserts at 11 a.m. and will extend until 9 p.m. Friday

Temperatures of 112 to 118 degrees are forecast for the deserts and highs could reach 105 degrees in the mountains, meteorologists said. A shallow marine layer will keep the coastal areas cooler.

Weather service forecasters said hot weather can be stressful for people and pets if precautions are not taken. Kids and pets must not be left unattended in vehicles because temperatures inside can quickly rise to lethal levels.

Strenuous outdoor activities should be rescheduled to early morning or evening hours, and those planning to spend time outdoors were advised to drink plenty of water and avoid alcoholic beverages.

  • 73 in Imperial Beach
  • 75 in Coronado
