PHOENIX -- A new set of heat-related warnings are in effect Tuesday after a near record-tying Monday. With a high of 108 degrees, we fell just one degree short of the record high for May 21, which was set in 2005.

Temperature gauges at the London Bridge in Lake Havasu City and at the Desert Botanical Garden beat that number, measuring 113 and 112 respectively.

The Phoenix area will be under another Excessive Heat Warning Tuesday, 10 a.m.-8 p.m.

The warning covers the lower deserts of southwest and south central Arizona. In addition to Phoenix, Casa Grande, Gila Bend, Yuma and Blythe are also included in the warning.

The average high temperature in Phoenix is about 96 degrees this time of year. Plan on a high of 107 degrees.

A Heat Advisory covers the area to the south, including the Tucson metro area.

The concern is that such hot temperatures can take a serious toll on the body -- something that can happen very quickly.

The National Weather Service suggests people take proper precautions, including limiting strenuous outdoor activities or rescheduling them to a cooler time of the day. If you have to be working outdoors during the heat of the day, schedule frequent breaks and be sure you have access to a shaded or cooled area.

In addition to wearing light-weight, loose-fitting clothing, the NWS suggests you wear a wide-brim hat when possible to shade your head.

The essential thing is to drink plenty of water to that you stay hydrated. It’s also important to know the signs and symptoms of dehydration and heat stroke.

These are likely to be the hottest days this week. Look for temperatures to drop of a couple of degrees each day. We should be back in the low 90s by this holiday weekend.

This hot weather isn’t just affecting the Phoenix area and locales south. It’s also affecting the northern area where firefighters area battling two of the biggest wildfires in the state.

The Crown King area, which is threatened by the Gladiator Fire, is under a Red Flag Warning between noon and 8pm today. That means high temperatures and low relative humidity. The winds that have been plaguing teams on the fire lines are expected to pick back up, with gusts of up to 35 mph. All of that adds up to hazardous fire weather conditions.

Temperatures are forecast to fall by the end of the week, with Memorial Day weekend looking sunny and warm with highs in the mid 90s.
