Flash Flood · Jun 12, 2021. A weak upper level disturbance moved along the northern side of an upper level ridge centered across the Desert Southwest generating thunderstorms over the mountains of Colorado and New Mexico. These storms slowly moved east into the Panhandles and encountered an environment with weak to moderate wind shear but extreme instability and high moisture which allowed these storms to thrive and increase in severity and…
Flood · Jul 4, 2021. A plume of monsoon moisture extended across the region and thunderstorms were ongoing in the morning of the 4th due to an Mesoscale Convective Vortex (MCV) moving southeast from the northeast Texas Panhandle into western Oklahoma. An upper level short wave moving south through western Kansas along with a surface trough across northeast New Mexico into the western Oklahoma Panhandle helped to spark additional show…
Flood · Aug 8, 2020. On the evening of August 8th a main area of thunderstorms moved from New Mexico and Colorado into the northwest combined Panhandles. Some storms trained across the same area just to the northwest of Highway 54 between Dalhart and Stratford. These training storms dumped 2 to 3 inches in a matter of an hour over an area just north of Conlen, TX. This led to some rural flooding.
Flash Flood · Jun 30, 2004. Heavy rainfall caused Carrizo Creek in extreme southern Dallam and extreme northern Hartley counties...west-northwest and west-southwest of Dalhart...to flood over the roads during the early morning hours.

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 Dallam 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.
