NWS Flagstaff

Forecast focus remains on Hurricane Rosa tracking north near the Baja peninsula. Sunday expect increasing clouds through the day as the storm grows nearer, though it will be a pleasant afternoon. Sunday night into Tuesday will be a very wet period across the region as the remnants of Rosa move into Arizona. Notice Rosa is forecast to remain at tropical depression strenth near Yuma on Tuesday morning, which is quite rare. The storm will pack strong winds and heavy rain on Tuesday as the core crosses the State. 

It has been an above average monsoon season for the majority of locations across Arizona. The summer rain has helped relieve the drought stricken land, coming out of one of the driest periods (fall '17 - spring '18) ever recorded. Here is a list of selected city rainfall totals and how it compares to normal (1981-2010 average).
