A low pressure system developed off the southeast coast and rapidly intensified as it tracked northward tapping into tropical moisture. The powerful low moved across eastern New York Sunday night into early Monday morning bringing damaging winds, power outages, heavy rainfall and flooding to the region. Several river flood warnings were issued with mainly minor flooding as a result. The exception was with Kast Bridge along the West Canada Creek, which crested at moderate flood stage but no impacts were noted.
As the system departed the region, strong winds ensued, causing thousands of power outages across eastern New York. Total rainfall from this system ranged from 2.0 inches in Rensselaer county up to 7.0 inches in Greene county.
The pressure at the Albany International Airport dropped to 28.82 inches as the low moved through. This sets a new record low pressure for the month of October.
