Some of Manhattan's most iconic spots would be submerged, including parts of Chinatown, SoHo and the financial district. Several feet of water would pool in the theater district and areas near MSG. In the Bronx, Yankee Stadium would be nearly surrounded by water, up to 11 feet in places.

Hurricane Erin’s remarkable strengthening continued on Saturday, and it could become a Category 5, forecasters said. Max sustained winds now at 155 m.p.h., and have increased by 80 m.p.h. over the last 24 hours — more then twice the definition of "rapid intensification." nyti.ms/3VahnQx

Rapid intensification is conventionally defined to be an increase of at least 35 mph in 24 hr. This is at 75 mph in 24 hr.
