National Weather Service Warns Of Excessive Heat, Dry Lightning In Arizona
The National Weather Service has placed most of Arizona under an excessive heat warning through Friday.
Looking at weather maps, meteorologist Marvin Percha said an easterly flow is expected to bring moisture, but no real showers.
"There's going to be storms, but mainly more dust and wind and for the east dry lightning," Percha said.
Their focus is mainly on fuel conditions that he says are very similar to conditions before the Yarnell Fire in 2013 and Dude Creek Fire of 1990. Both wildfires started by dry lightning strikes.
"The entire state is under either extreme or even worse drought condition," Percha said.
And, he said the risk is all across the state," where the concentrations of fuels are further up, but even the parts of the lower deserts, the north and east periphery of the greater Phoenix area could see fire starts."
Good luck getting away from the sweltering heat. Forecast models show the excessive heat warnings span clear across the Southwest as the moisture build.
For instance, he said, "San Diego is forecasting highs of 95 and even Coronado Island a high of 86, so even the beach communities are going to be quite a bit warmer than normal."
Percha says stay indoors and if travel is necessary, bring plenty of water to stay hydrated.
If driving, he urged motorists to check that nothing is dragging from the vehicle and avoid driving over dried grass and vegetation where hot tailpipes can start a fire.
