Flash Flood · Jul 30, 2025. Heavy rain, 1.5 to 3 inches, produced flooding in and around Ypsilanti, Canton, and Northville.
Flash Flood · Jul 28, 2025. A very warm and humid airmass supported the development of thunderstorms. Weak winds aloft limited storm motion speeds leading to some stationary storms that produced flooding. One storm developed right over Detroit Metro Airport, producing 2.68 of rainfall in 2.5 hours which lead to flash flooding. Additional storms near Sterling Heights produced radar estamited 3 inches of rain, which also led to flash flooding.…
Flood · Apr 2, 2025. Morning snow, light freezing rain, and some sleet transitioned to rain showers and thunderstorms by midday on April 2nd. An anomalously warm and humid low-level air mass moved into Lower Michigan while the surface warm front lagged well to the south, over the Ohio Valley. Numerous rounds of repeated rainfall during the day and overnight led to several areas across Metro Detroit receiving between 2 and 3 of rainfal…
Flash Flood · Jul 23, 2024. A few severe thunderstorms developed along the M-59 corridor, producing both hail and damaging winds, with flooding also occuring over parts of Macomb and Wayne counties. Rainfall totals of 2 to 2.5 inches were observed over a short period.

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Wayne County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.
Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
