Big weather changes move into in Arizona as the remnants of two tropical systems combine with an approaching Pacific storm, resulting in several days of rain.
Due to the widespread impacts, Friday and Saturday are ABC15 Weather Action Days.
Our best chances for widespread, heavy rainfall will be Friday through Sunday.
Isolated thunderstorms are possible over the next couple of days. These could bring strong winds, lightning, small hail, and quick-hitting downpours which could lead to localized flooding.
A Flood Watch is in effect for much of Arizona through Saturday evening. A separate Flood Watch begins Saturday afternoon for southeastern Arizona, including Tucson and Safford, and continues through Monday afternoon.
Since the rain may fall over a long stretch, washes and small creeks could start flowing, and some low-lying spots may see localized flooding.
