How Crawford County floods

Flash flooding from summer thunderstorms and spring snowmelt dominates the flood character of Crawford County, PA. Over the last 30 years, the NOAA Storm Events Database recorded 63 flash flood events resulting in 1 death, alongside 15 standard flood events. Historical events demonstrate how weather patterns trigger these incidents. For example, flooding occurred throughout much of the county from February 17th through 19th, 2022, due to above-normal temperatures melting a snow pack combined with 1 to 2 inches of rainfall, causing flooding along French Creek and Cussewago Creek that was exacerbated by ice jamming. Additionally, saturated soils and slow-moving thunderstorms dropped over 2 inches of rain in a one-to-two-hour period over far southeast Crawford County on July 17th, 2021.

Properties located near rivers and streams, as well as those mapped in FEMA flood zones, should pay the most attention to these risks. NFIP claims data shows that Zone A properties experienced the highest impact with 191 claims, averaging a $7,275 payout and an average recorded water depth of 9 inches. Meanwhile, properties in Zone X recorded 37 claims with an average payout of $9,744 and an average recorded water depth of 12 inches, while Zone UNKNOWN recorded 70 claims averaging a $2,584 payout with an average recorded water depth of 3 inches. Zone X_UNSHADED recorded 19 claims averaging a $6,564 payout with an average recorded water depth of 2 inches, and Zone X_SHADED recorded 13 claims averaging a $9,058 payout with an average recorded water depth of 3 inches.

From the storm reports

Flood · Feb 17, 2022. Flooding was observed throughout much of Crawford County during the February 17th-19th, 2022 timeframe. This was due to above normal temperatures causing steady melt of a snow pack containing 2 to upwards of 3 of water equivalency up through the daytime hours of the 17th, and rainfall amounts of 1-2 on top of the melting snow. Flooding of French Creek and tributaries was observed, including Cussewago Creek, which…

Flash Flood · Jul 17, 2021. A warm, unstable airmass has been in place over the region for much of the week leading up to July 17th, 2021, with several rounds of rainfall during the week leading to saturated soils across northwest PA. Thunderstorms developed ahead of an eastward moving cold front, with low echo centroid storms providing efficient, heavy rainfall. Two storms tracked over far southeast Crawford county in PA, dropping over 2 of…

Flash Flood · Jul 11, 2021. Low pressure was slowly moving northeast from IN through northern OH during the day of July 11th, 2021, lifting a warm front northward towards northwest PA. Showers and thunderstorms moved northeast across Erie County, PA for much of the daytime hours ahead of this front. An low echo centroid storm with intense rainfall rates around 1.5 per hour produce efficient heavy rainfall over an area with saturated soils fr…

Flash Flood · Jul 19, 2019. A backdoor frontal boundary was moving slowly northeast to southeast across northwest Pennsylvania during the evening of July 19th. A line severe thunderstorms blew down trees across rural Crawford County.

Flood insurance in Crawford County

If a building in Crawford 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.
