Monsoon thunderstorms threaten Valley tonight
It may be off to a slow start, but the Arizona Monsoon is edging closer to the valley tonight. The National Weather Service in Phoenix reports a 40% chance of showers and thunderstorms this afternoon, with storms likely mainly before 11:00 p.m.
Strong winds may accompany thunderstorms with large areas of blowing dust.
A flood advisory has already been issued for most of South-East Arizona including the Tucson area after heavy rains there last night.
