Southern Arizona readies for monsoon season

Posted: Updated:


TUCSON, Ariz. (AP) — The National Weather Service says the monsoon season officially arrives in southern Arizona on Tuesday, but it could be a while longer before the region sees its regular dose of moisture.


Forecasters say the actual onset of the monsoon isn't expected until the first week of July.


It's the Super Bowl of weather events in southern Arizona — a 108-day period when the region receives half of its yearly rainfall and almost all of its lightning strikes, along with damaging winds and flash floods.


Meteorologist Erik Pytlak says these storms can be dangerous.


Pytlak spent early June testing his ability to predict the movement of summer thunderstorms and issue watches and warnings for affected areas.


The weather service is predicting an equal chance of above- and below-average precipitation for the 2010 monsoon.
