How Hennepin County floods

Flash flooding from summer thunderstorms dominates the flood risk profile in Hennepin County, Minnesota, accounting for the vast majority of recorded flood events over the last 30 years compared to general floods.

Recent historical data illustrates this threat. On June 16, 2025, multiple rounds of storms produced large hail, funnel clouds, and tornadoes. Shortly after, on June 25, 2025, strong surface heating and a lifting warm front brought high dew points, instability, and scattered thunderstorms that caused flash flooding across western and east-central Minnesota.

Property owners and real estate professionals should note that insurance claims and payouts occur across both designated high-risk and moderate-to-low-risk areas. Specifically, properties in FEMA Zone A recorded 247 claims with an average water depth of 4 inches and an average payout of $11,616. Meanwhile, properties in Zone X recorded 190 claims with an average water depth of 5 inches and an average payout of $12,822, and Zone X Unshaded recorded 114 claims averaging 5 inches of water depth and a $13,096 payout. Consequently, homeowners and real estate agents in both designated flood zones and standard unshaded zones should pay close attention to local drainage and flood preparation.

Where the flood claims came from

37% of Hennepin County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.

390 NFIP claims with a recorded rated flood zone, 1978 to date. The zone is the one FEMA used to rate that policy, which may not match today’s map. Source: OpenFEMA NFIP claims.

From the storm reports

Flash Flood · Jun 25, 2025. A warm front lifted north into southern Minnesota on the afternoon of Wednesday, June 25th. Strong surface heating to the south of the front with dew points in the 70s allowed for ample instability to develop across the area. Scattered thunderstorms developed in response to the instability and flash flooding occurred in western and east central MN. Strong low-level shear allowed these low-topped supercells to rot…

Flood · Jun 16, 2025. Multiple rounds of storms produced several cases of large hail and funnel clouds, as well as two tornadoes in Nicollet county during the afternoon and evening on Monday, June 16th. The largest reported hail (3.25 inches) occurred with a storm the developed over McLeod county and quickly strengthened over Carver county. There was also significant wind damage in the St Cloud area.

Flash Flood · Jul 16, 2019. Thunderstorms developed during the afternoon of Tuesday July 16th across southern Minnesota. A few storms developed over the Twin Cities metro area and produced torrential rainfall, and flash flooding around the west, and southwest side of the downtown Minneapolis area.

Flash Flood · Jul 15, 2019. Several clusters of thunderstorms developed during the afternoon of Monday, July 15th in central Minnesota. A few storms also developed ahead of the storms in central Minnesota, and became severe west of the Twin Cities. Hail stones as large as 2 inches in diameter were reported around Delano, and the western suburbs of the Twin Cities. By the late afternoon, and into the evening, these storms become more wind pro…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Hennepin County

If a building in Hennepin 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.
