UPDATE: Weather Historian Chris Burt says via email: "The official pressure record for the NE is 27.94" at Bellport Coast Guard Station on Long Island (during the 1938 hurricane of course)."
UPDATE: The 12Z GFS computer model raised the minimum pressure of Hurricane Sandy (over water) from 938 mb to 948 but it now has Hartford tying the record pressure of 28.04" from 1920 on Tuesday morning!
Please read my earlier blog Sandy: A Few Good Men Vs. the Storm of the Century for insight into meteorologists and this storm. Stay tuned to AccuWeather.com for the latest news updates and watch my Facebook Page for additional information.
ORIGINAL ENTRY: The pressure readings that the 00Z ECMWF (Euro) model is printing out will threaten city and state low pressure records, if it verifies. Looking just at Virginia, Maryland, Delaware and New Jersey, all their records would be shattered by Sandy. BUT: Historical pressure readings are recording for only a couple cities per state. Baltimore, MD and Wilmington, Delaware would break their (and therefore their states) all-time pressure records.
For the 00Z GFS model, which has a more northern landfall, New York City, Block Island, RI and Nantucket, MA would break their all-time low pressure readings. The all-time Northeast U.S. low pressure reading (28.04" in Hartford, Connecticut, according to weather historian Chris Burt) would be safe, at Hartford, CT, which would only fall to 28.17", but other places in the state would tie that record.
As much as 27 inches of rainfall has closed I-95 in South Carolina, as well as nearly 400 other roads and 165 bridges!
Over 17 inches of rain fell near Columbia, South Carolina just last night!
The extreme rain continues today, with the Carolinas in the cross-hairs. This one could be a 1,000 year event.
Hurricane Joaquin rapidly strengthened into a monster storm overnight -- this changes everything.
Will Hurricane Joaquin be the next "Isabel" or "Sandy?" Does it even matter?
It's not a matter of "if" but "where" the flooding footage you'll see on the news later this week will be from.
