Phoenix, Arizona
A significant storm is set to impact Phoenix and much of Arizona from Friday through Sunday morning, as heavy rainfall is expected due to tropical moisture from the remnants of Hurricane Priscilla. Arizona’s Family has declared First Alert Weather Days for this period as the state braces for flooding and stormy conditions.
A flood watch will be in effect for northern Arizona from Thursday through Saturday. Residents in affected areas should prepare for possible flooding of rivers, creeks, low-lying areas, and streets with poor drainage. The system could bring rainfall amounts exceeding 2-3 inches, especially in southern Arizona, with particularly heavy rain anticipated on Saturday and Sunday. A separate tropical system may develop early next week, bringing even more rain.
To address potential flooding, the Disaster Assistance Center will reopen on Saturday and Sunday from 9 a.m. to 7 p.m. at Lee Kornegay Intermediate School. Residents may need to fill their own sandbags, as some locations may require this for effective flood protection. Proper sandbagging techniques should be followed: bags should be filled slightly more than halfway to prevent openings for water to seep through, and bags should be stacked in a brick pattern to achieve a height of at least 3 feet.
The weather leading up to the storm has seen high temperatures in Phoenix reaching 100 degrees, above the average of 92 degrees for this time of year. Scattered showers are expected to move in from the south starting Wednesday night, with the possibility of thunderstorms featuring strong winds, lightning, small hail, and brief downpours. Although rain chances will decrease later on Sunday, light to moderate rainfall is projected for the remainder of the weekend.
Flash flooding is a major concern, particularly in areas that are typically susceptible to flooding. Dry washes and creeks are expected to flow as the rainfall accumulates. While high temperatures are expected to hover around 100 degrees through Thursday, a significant drop into the 80s is forecasted for the weekend due to the cooling effect of the incoming rain.
This weather pattern serves as a reminder for residents to stay alert and take necessary precautions as Arizona prepares for this influx of moisture. The storm is anticipated to provide much-needed water to the region but also presents hazards that require careful attention.
