Last Wednesday's snow storm came with strong northwestern winds. This caused a dramatic blow out tide in the Hudson Estuary that could be seen from Schodack Island to the Battery. Water levels dropped by four feet or more. Luckily these conditions were predicted by the NYHOPS forecast. One Hudson River Pilot was particularly greatful, "The ship was loaded to 31 feet and the channel normally is 32 feet deep. A dramatic drop in water level has a significant effect. You might be scraping the mud as you go along and it handles very very poorly." For a more detailed description, see this story describing blow out tides.
