Weekend Warm Up is Precursor to Triple-Digit Workweek

Published : Saturday, July 21, 2018 | 5:06 AM

This weekend’s warmup is just a preview for what’s in store next week, forecasters predict, saying Pasadena should wind up to the lower 90’s on Saturday and Sunday before breaking through to triple digits possibly by Monday.

An Excessive Heat Warning will be in effect starting Monday at 10 a.m. and is expected to stay in place until 8 p.m. Thursday, July 26, according to the National Weather Service.

Saturday should be sunny, with a high near 90 and a calm wind becoming south southwest around five mph in the afternoon. Saturday night should be mostly clear, with a low around 68 and a south southwest wind around five mph becoming calm in the evening.

Sunday should be sunny, with a high near 92. Sunday night should be mostly clear, with a low around 69.

Monday should be sunny and hot, with a high near 99. Monday night should be mostly clear, with a low around 72.
Tuesday is expected to hit 101, Wednesday 102, Thursday 101, and Friday to drop down to 98.

If you plan to be outdoors, take precautions by hydrating more than usual, avoiding the sun from 10 a.m. through 3 p.m., reducing physical activity, wearing wide-brimmed hats and light-colored lightweight, loose-fitting clothes, health experts say.

During periods when the Excessive Heat Warning is in effect (now expected to be called Monday), be prepared for an increased potential for serious heat-related illnesses, especially for the young and elderly, those performing outdoor activities, as well as those without access to air conditioning, the National Weather Service said.

There could also be an increased potential for power outages. In past heat waves, Pasadena Water & Power has been known to pre-position equipment and to place additional crews on stand-by to deal with that possibility.

“Never, ever, leave people or pets in enclosed vehicles, even for a short period of time. Take extra precautions if you work or spend time outside,” the National Weather Service said.

“When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. 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.”
