Flash Flood · Sep 25, 2025. A low pressure system of tropical origin moved northward into the area and combined with deep moisture to produce an afternoon of thunderstorms. These storms produced accumulating hail and heavy rainfall.
Flood · Dec 31, 2022. The strongest winter storm of December passed through the region on the final two days of December. This storm initially produced very high snow levels near 9000 feet on 30 December. Colder air and enhanced forcing, coupled with the final push of extensive moisture worked in unison to rapidly drop snow levels to most valley floors (above 4000 feet) during the morning of New Years Eve. Although this early change-o…
Flash Flood · Sep 12, 2022. Isolated strong thunderstorms with concentrated heavy precipitation cores that initiated along the eastern Sierra caused periods of flash flooding and debris flows in and around the Holbrook Junction area that also closed Nevada SR167 (Highland Way) to the Cal-Neva state line as well.
Flood · Aug 4, 2022. A deep layer of monsoonal moisture pushed northwest and north into California, Sierra, and western Nevada in a southerly upper flow that marked the western margins of an area of strong high-pressure ridging into the Great Basin region. Thickening mid-level moisture coupled with steep afternoon lapse rates and warmer surface heating initiated deep columns of slow-moving moisture-laden showers and thunderstorms wit…

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 Douglas 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.
