From the storm reports

Flood · Jan 25, 2010. Heavy rainfall between 1 and 4 inches produced widespread areal flooding across all of central Pennsylvania. Cold season hydrologic conditions, including snow and ice melt contributed to enhanced run-off especially across the higher elevations and northern mountains. Many small streams and creeks came out of their banks, resulting in numerous secondary road closures.

Flood · Dec 1, 2010. Widespread heavy rainfall of 2 to 4 inches produced extensive flooding across Central Pennsylvania for the first three days of December 2010. The heavy rain fell in two distinct periods with the first round of 1-2 inches falling by the evening of November 30th. The second period of heavy rain fell overnight into the afternoon on December 1st. The initial rainfall on the 30th resulted in antecedent conditions that…

Flood · Nov 19, 2003. Heavy rain caused rises in streams, and produced flooding. This closed roadways across the county, including Route 120.

Flash Flood · Nov 19, 2003. Heavy rain caused rapid rises in streams, and produced flash flooding. This closed roadways across the county including Route 120.

Flood insurance in Cameron County

If a building in Cameron 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.
