Moisture from Hurricane Polo is fueling a flash flood threat in the Southwest this week even though the storm itself won’t reach the region. Rainfall totals could reach up to 5 inches by Wednesday. The heavy rain will fall on rocky soils, burn scars and slot canyons, which can contribute to the potential of flooding.
