Sunday storms trigger new round of alertsPosted: Updated:
One day after the monsoon delivered another dangerous dose of weather, conditions ripened for round two Sunday.
The greater Phoenix area and northwest and north central Pinal County were under a dust storm warning that expired at 7 p.m.
For one hour and 45 minutes, Sky Harbor International Airport was under an airport warning for lightning and high winds.
Forecasters warned people for the possibility of sustained 20 mph winds with gusts to 40 mph.
For a time, a flash flood warning covered central Maricopa County, mainly Ahwatukee, Tempe, Sun Lakes, Mesa, Gilbert and Chandler.
Near Magma, near one-half inch of rain fell in 17 minutes, according to a National Weather Service spotter.
When the storm moved through Queen Creek, it was accompanied by gusty winds and a little bit of hail, according to one CBS 5 viewer.
In Fountain Hills, there were reports of a number of trees uprooted, as well as toppled power poles.
A flash flood watch is in effect through late Sunday for a portion of southeast Arizona, including southeast Pinal County.
In the greater Phoenix area, there is a 60 percent chance of showers and thunderstorms Sunday night. Rainfall between a quarter and a half of an inch is possible, except locally higher in thunderstorms, meteorologists said.
A very moist and unstable atmosphere led to the development of showers and thunderstorms Sunday afternoon and night. Some storms could linger into the early morning hours of Monday, forecasters said.
Many of these storms will be capable of producing very heavy rain in a short period of time, increasing the threat of flash flooding.
Any thunderstorms that do develop will bring potentially deadly lightning, strong gusty winds and heavy rain with localized flooding.
Arizona's monsoon season began June 15 and runs through Sept. 30.
