Large portions of Arizona are under a flood watch through Tuesday evening as the remnants of Hurricane Polo track inland from the Pacific. While precipitation will hit the Phoenix metropolitan area, meteorologists warn that the highest risk for flash flooding is concentrated in the state’s northern and southeastern regions.
High-Terrain Flash Flood Warnings
The National Weather Service (NWS) has identified Arizona’s higher terrain as the primary area of concern. The atmospheric moisture trailing Hurricane Polo is expected to concentrate in these elevated areas, resulting in heavier rainfall totals.
Gabriel Lojero, a meteorologist with the NWS, warned that the depth of floodwaters is often deceptive. He emphasized that attempting to cross these waters can lead to vehicles becoming stranded.
Roadway Safety and Motorist Advisories
Authorities have issued a standard safety advisory: if you encounter flooded roads, do not attempt to drive through them.
Residents are urged to monitor local alerts through the National Weather Service, as conditions in mountainous terrain can shift rapidly.
Wednesday’s Shift to Clear Skies
The Valley should see a transition to drier conditions by Wednesday. According to the NWS forecast, skies will clear, ushering in a period of quiet, mostly sunny weather for the remainder of the week.
El Niño and Winter Precipitation Outlook
Beyond the immediate impact of Hurricane Polo, the National Oceanic and Atmospheric Administration (NOAA) is monitoring strong El Niño conditions in the Pacific. These patterns historically correlate with wetter-than-normal winters for the Desert Southwest.
While an increase in seasonal precipitation is not a certainty, the current climate pattern suggests a higher likelihood of above-average rainfall for Arizona in the coming months. Residents are encouraged to remain aware of long-term forecasts and potential flood risks throughout the winter.
