From the storm reports

Flash Flood · Jan 30, 2025. A slowly lifting warm front across Arkansas led to a significant rain event across central and northern Arkansas during a period of several days. Rainfall totals mounted across the northern half of the state and by January 30th locations across central and northern Arkansas experienced Flash Flooding after receiving additional rainfall.

Flash Flood · Jun 19, 2025. An approaching cold front and enough CAPE within the warm sector along with favorable lapse rates would lead to a few instances of hail and flash flooding across central Arkansas.

Flash Flood · Jun 15, 2025. A stationary front across the Mid-West portion of the CONUS led to a ample warm sector with plenty of moisture and warm air streaming into the Natural State which led to multiple days of severe weather which included tornadoes, wind damage, and several instances of flash flooding across the state as Arkansas saw several days of moderate to heavy rainfall.

Flash Flood · Apr 5, 2025. Severe weather, including widespread flash flooding occurred over a five day period across the entire state. This multiday event featured tornadoes, damaging winds, and very large hail. But by far and large, flash flooding and river flooding were the biggest impacts taken away from this unsettled period of weather due to total rainfall amounts between half a foot to over one foot in many locations.

Flood insurance in Montgomery County

If a building in Montgomery 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.
