MM’s Sun Wx Forecast for Sept 4

Flash flood watch for Sunday and Monday.
On September 4, 1964 the OGO 1 launch took place. It was the first Orbiting Geophysical Observatories mission designed to conduct numerous space experiments simultaneously. The images above captured during asteroid survey operations on Tuesday, August 25, by the University of Arizona’s Catalina Sky Survey and shows that observatory as it was getting ready to crash back to Earth in August of 2020.

Wx Summary

A flash flood watch is in effect for Sunday and Monday. Be careful if you’re around waterways today. Even the most harmless of streams can turn deadly during a flash flood. And NEVER drive across flooded roadways, especially if the water is moving. Most flood deaths occur in vehicles. Even on the plateau we face the risk from the dangers of flash floods. Water on the plateau can rise quickly and water often falls quickly, but if you lose your life during the high water it doesn’t matter how quickly that water recedes.

Rain and storms will dominate the rest of our Labor Day weekend. Some of that rainfall will likely be heavy and cause flash flooding. Rain chances continue beyond Labor Day and throughout all of next week.

MM’s Severe Wx Concerns 

If you make outdoor plans through Labor Day please keep an eye on the radar and have an indoor back-up plan. The greatest threat for today and tomorrow is flash flooding. If you’re out driving and encounter heavy rainfall be safe on those roads. Remember, never drive across flooded roadways, especially if that water is moving. If you live near a flood-prone area be ready to seek higher ground quickly.

HRRR Radar Model

This radar model runs from 9:00 a.m. to 9:00 p.m. in one-hour increments and does a good job showing the trend expected for today.

On This Day 

1986- Murfreesboro records its greatest one-day rainfall ever, measuring 8.13″.

1970 – The greatest natural disaster of record for Arizona occurred. Unprecedented rains caused rivers in central Arizona to rise five to ten feet per hour, sweeping cars and buildings as far as 30 to 40 miles downstream. Flooding claimed the lives of 23 persons, mainly campers, and caused millions of dollars damage. Water crested 36 feet above normal near Sunflower. Workman’s Creek was deluged with 11.40 inches of rain in 24 hours to establish a state record. Moisture from Pacific Tropical Storm Norma led to the severe flooding. (4th-6th) 

1986 – An unusually strong dust devil moved across the Flagstaff Pulliam Airport. The dust devil blew open the doors of the National Weather Service office scattering papers and bringing down a ceiling-mounted light fixture.
