AZWF Flood Watch Upgraded to Flood Warning to Maricopa and Pinal County Now Through Tuesday


Arizona Weather Force’s early Flood Watch for half of the state has now been narrowed down to issue and upgrade to the rare wintertime Flood Warning alert.  This alert will be for Maricopa and Pinal County’s most populated areas from the Phoenix Metro to the San Tan Valley zones.

A storms system that has already caused major flooding in San Diego and Imperial County continues to move east.  Yuma has reported a lot of flooding.  As I continue to follow the dynamic, I can say now that overnight will be bad for the warning area, especially if you always get flooded during monsoon events.  A rare event yes, but the watch I issued earlier should have prepared you enough for it.

National Weather Service Phoenix has failed to warn your forecast area of the type of flooding this is.  I stand by the high risk from my own model as in many who do not see this will be caught off guard.  If they issued a Flood Watch now, it is too late.  It is dark now and this is an overnight event for the heaviest activity.

With this watch, thunderstorms will also be likely, which will up the totals.

Storm activity will continue into Tuesday as the storm sits right over the Maricopa County area.  This means that off and on thunderstorms are likely.  This is the center of the low-pressure system, which has a cold core with it.  This means that there is a chance that out of nowhere a funnel cloud can touch the ground as a tornado.  You just have to look for it.

That is it, the long range numbers from me suggests first week of February will be another pattern and also a much colder one for Arizona.
