From the storm reports

Flood · Feb 15, 2025. Showers and thunderstorms produced heavy rainfall (2-5) as they streamed northeast across southeast Missouri in the afternoon and evening of the 15th. The greatest rainfall amounts were near the Mississippi River in New Madrid and Mississippi counties. Minor flooding of city streets occurred in the city of New Madrid and along numerous state highways and county Roads. The heavy rain caused a retaining wall to coll…

Flash Flood · May 26, 2024. The second major severe weather outbreak for the month occurred on the 26th for the Quad State region. On the synoptic scale, a shortwave trough centered in the middle of the country with a 60 kt mid-level jet moved across northern Arkansas. A weak surface low was moving into SE Missouri during the morning with a secondary low located further northwest. A warm frontal boundary was draped across our area. A bowing…

Flash Flood · Jul 8, 2024. Convection developed during the afternoon of the 8th with activity most widespread between 1200-1700CST. PW values of 2-2.25 inches, bolstered by moisture from Hurricane Beryl to the southwest, resulted in torrential rainfall rates that produced isolated flooding issues. Additionally, a landspout formed south of I-57 in Mississippi County, reported via several photos and videos. Effective bulk shear was roughly 30…

Flood · Jul 5, 2024. Elevated water levels flowing down the Mississippi River from locations north of the Quad State resulted in minor flooding on the Mississippi in Southeast Missouri from early to mid July. Impacts were mostly limited to low-lying agricultural areas.

Flood insurance in Cape Girardeau County

If a building in Cape Girardeau 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.
