How Forest County floods

Flash flooding from summer thunderstorms dominates the flood risk profile in Forest County, Pennsylvania, accounting for the majority of the 17 recorded flood events over the last 30 years, alongside 5 general flood events.

Historical events illustrate these varying causes. In June 2014, thunderstorms moving over already saturated ground led to flooding of streams, creeks, and poor drainage areas. Earlier, in February 2009, a combination of snowmelt and rainfall caused flooding due to ice jams across parts of northwest Pennsylvania.

National Flood Insurance Program claims data indicates that properties situated in FEMA Flood Zone A carry the most significant risk, accounting for 9 claims with an average payout of $26,008 and an average recorded water depth of 19 inches. Homeowners, real estate agents, and journalists should pay the closest attention to properties located within Zone A, as well as those near streams, creeks, and areas prone to poor drainage.

From the storm reports

Flash Flood · Jul 4, 2019. With very moist profiles and little wind shear, the primary concern for the day was heavy rainfall and localized flash flooding potential with thunderstorms. A flash flood watch was issued for a portion of our region, mainly the higher elevations. Deep warm cloud depths and slow moving storms promoted high rainfall rates. The 00Z sounding noted very high precipitable water values of 1.67 inches, which exceeded the…

Flood · Jun 13, 2014. Thunderstorms moving over already saturated ground lead to flooding of some streams and creeks as well as areas of poor drainage.

Flood · Mar 6, 2011. A low pressure system, moving from the plains to the Ohio Valley, brought widespread rainfall of 1 to 2 inches over western Pennsylvania beginning Saturday March 5th, and lasting through Sunday morning, March 6th. Area streams and creeks rose in response to this rainfall causing localized flooding in Venango and Forest counties. Rain then transitioned to snow Sunday with snow totals of 7 to 10 inches over the moun…

Flood · Feb 12, 2009. A combination of snow melt and rainfall caused flooding due to ice jams across parts of northwest Pennsylvania.

Flood insurance in Forest County

If a building in Forest 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.
