A flash flood watch means flooding is possible. The more serious flash flood warning means flooding is about to happen, or is already happening.
Chances for heavy rainfall increase from Tucson eastward, beginning late Thursday morning through Saturday evening, the National Weather Service said.
The chance of rain here diminishes next week, but it is still possible mostly south and east of Tucson.
