Heat and humidity began building across a wide swath of the nation on Friday as dozens of cities declared heat emergencies and excessive heat warnings and advisories were posted by the National Weather Service. However, the most extreme days in the heat wave are likely to be on Saturday and Sunday for many areas.
Power companies have braced for a surge in energy consumption as close to 100 million Americans live in an area where a daily record-high temperature could be set on Saturday, when the heat wave peaks.
Until the pattern breaks, strenuous physical exercise and manual labor should be limited. If these activities must take place, they should be avoided during the hottest part of the day and frequent breaks from the heat are highly recommended. Remember to increase the intake of non-alcoholic fluids and frequently check on young children and the elderly.
Today we’re seeing a high of 90 degrees and a heat index of 101 degrees. Tomorrow and Sunday we’ll see a high of 97 degrees with a heat index of 111 and 110 respectively.
This kind of heat can be dangerous — keep cool, keep hydrated, keep inside if you can. pic.twitter.com/7Og0FRsuCO
