Scorching heat wave to test people, power systems

Extreme heat conditions will continue across the Las Vegas region through Tuesday evening.

Temperatures will be 8-12 degrees above normal at all hours of the day with early morning lows staying above 80 in most locations, according to the National Weather Service forecast.

An excessive heat warning covers all of Southern Nevada (except high elevations) and adjoining counties to the north as well as northwest Arizona and southeast California. A heat advisory covers parts of central Nevada.

There is a chance Friday of some high elevation storms well south of Las Vegas.

Visitors and residents are reminded that prolonged periods of excessive heat will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities.

Those without access to adequate or reliable cooling or hydration will be at most risk, but much of the population could be susceptible to impacts as well.

Labor Day may be hottest at 111

The Friday high in Las Vegas is forecast to be 109, which is what the Thursday high reached. The mercury stayed at 100 or above for 12 hours on Thursday.

Saturday morning should drop to around 85 with an afternoon high near 108.

Sunday will likely be a bit warmer and Monday is expected to be the hottest day of the spell at 111.

Clark County cooling shelters will be open each day except Labor Day, when most are closed. Check here for details. The City of Las Vegas in a tweet stated the expanded Courtyard Homeless Resource Center is a safe place for the homeless to escape the heat 24/7. The address is 314 Foremaster Lane.

NV Energy has asked users to conserve electricity, especially from 5 to 8 p.m.
