A passing cold front will bring much cooler conditions tonight into tomorrow. This cold front is projected to stall offshore, bringing more potential rain to the area Thursday. All eyes are on the potential impacts of Joaquin in the near future – the short term risks involves a northeasterly wind causing coastal flooding on the south shore of Long Island and minor flooding into New York Harbor, as well as a constant threat of rain. Rain totals up to Friday night could exceed 2-3 inches. Winds will be steadily increasing over the next few days as a result of a tightening pressure gradient between a strong Canadian high and Joaquin.
Potential flooding impacts are very possible due to this prolonged period of rain. An increase in winds and saturated ground can cause significant damage to infrastructure due to downed trees and power lines. Coastal flooding is almost inevitable due to long term northeasterly flow and a tightening pressure gradient.
