Overview
Tropical moisture, brought up by the remnants of Hurricane Beryl, dropped quite a bit of rain over Southeast Michigan over a 48-hour timeframe. Rain began across parts of the county warning area (CWA) on Tuesday, July 9th and continued through the day on Wednesday, July 10th. By the time the remnants of Hurricane Beryl moved off to the east, measured rainfall amounts were in the 2 to 6 inch range, with the highest amount of 7 inches east of Flint in Genesee County. The center of the post-tropical system tracked just to the south of Southeast Michigan as it made its way off to the northeast. Winds also accompanied the system, with wind gusts in the 30-35 mph range.
The official climate site at Flint Bishop Airport, broke their daily (24-hour) rainfall total on July 10th with 3.27 inches breaking the previous record of 1.63 inches set back in 1970.
This is the first post-tropical system to impact the local area since the remnants of Tropical Storm Cristobal in 2020. Other past tropical impacts are listed here.
