PHOENIX -- Triple-digit temperatures continue to inch upward in Arizona's desert cities, prompting concerns about how some people will fare in the summer heat.
The National Weather Service's Phoenix office is forecasting above-average highs through the weekend with little or no chance of precipitation. And, ``only a modest cooling trend should be expected early next week,'' the service cautioned.
The forecast highs include 109 in Yuma and 110 in Phoenix on Friday and 114 in both Lake Havasu City and Bullhead City on Saturday. Tucson is forecast to reach 106 both days.
That kind of heat can be deadly under the wrong circumstances.
Seven children have died in other U.S. states over a 16-day period in May after being left in hot cars, the Phoenix Fire Department said in announcing a prevention campaign that includes putting warning stickers on convenience store windows.
In Mesa, city officials for the seventh year are conducting a campaign to collect thousands of bottles of water to help homeless people and others in need.
``We have encountered people near death in 115-degree heat in the parks. Fortunately we have been able to carry water donated during the campaign to revive them before calling firefighters and paramedics for emergency help,'' Park Ranger John Goodie said.
It's not only the desert cities that are parched.
Flagstaff in northern Arizona's pine country has gone 90 days without significant precipitation aside from just under an inch of snow on May 9, the Arizona Daily Sun reported.
``We've been so dry so far and we're headed into the driest month, but you never know, we could have a wet June,'' said Robert Rickey, a meteorologist with the National Weather Service in nearby Bellemont.
