See PA hazardsPA hazard profile
Pennsylvania's river systems are among the most flood-prone in the East. The Susquehanna, Delaware, Schuylkill, and Allegheny all have catastrophic flood histories. Agnes (1972) killed 48 Pennsylvanians. Lee (2011) caused $1B+ in damage along the Susquehanna. Central PA river communities — Harrisburg, Wilkes-Barre, Sunbury — flood with every major rainfall event. Flash flooding in mountain valleys can be sudden and deadly. Philadelphia and eastern Pennsylvania are in the direct path of nor'easters — powerful coastal storms that bring heavy snow, ice, and wind. The January 1996 blizzard dropped 30 inches on Philadelphia in 48 hours. Pittsburgh and western PA get significant Great Lakes-influenced snowfall. The Pennsylvania Turnpike closes multiple times per winter in mountain sections. Pennsylvania averages 16 tornadoes per year, concentrated in the western and central parts of the state. The May 31, 1985 outbreak killed 65 Pennsylvanians and is one of the deadliest tornado outbreaks in state history. The Pittsburgh and Erie corridors are the most active. Spring season (April–June) is peak.
Flash floods, river flooding, and coastal surge affect low-lying areas and river corridors.

Flood damage — requires NFIP or private flood policy
Earthquake damage — requires separate endorsement
Sewer & drain backup — requires endorsement ($50–$100/yr)
Landslide / mudflow — generally excluded
