[Cross posted from Foot’s Forecast: The Tropical Zone, time is short, info current as of 8 AM EDT]
Good morning folks. We hope you are as prepared as you can be. If not, you should be finalizing your preparations as time is running out for you to do so. Heed all warnings and advisories issued by your local weather service and media outlets. Sandy is now expected to be a ‘strong Category 1 Hurricane with winds of 90 mph at landfall’. At this time we have determined Sandy [the center] will make landfall in the area of northern Delaware and Southern New Jersey, in the Delaware Bay early Tuesday morning. When Sandy goes Post-Tropical later today, the Foot’s Forecast: Severe Storm Center will be issuing updates and they will be shared with Foot’s Forecast: The Tropical Zone.
Currently – Winds: 85 mph | Pressure 946 mb | Location: 36.8N 71.1W (310 miles South-southeast of New York City New York and 265 miles Southeast of Atlantic City New Jersey) | Moving North-Northwest at 20 mph. Currently Tropical storm force winds extend out 485 miles and Hurricane force winds out 175 miles from the center. Sandy will be felt long before the center makes landfall. A tropical Storm ‘Warning’ is in effect from Cape Fear to duck North Carolina, Pamlico / Albemarle sounds and Bermuda.
Hurricane force winds are expected between Chincoteague Virgina and Chatam Massachusetts including the Tidal Potomas from Cobb Island to Smith Point, the Middle and Upper Chesapeake Bay, Delaware Bay, The coasts of the Northern Delmarva Peninsula, New Jersey, New York City, Long Island, Connecticut and Rhode Island. Tropical storm Force winds are expected North of Chatam to the Merrimack River Massachusetts, the Lower Chesapeake Bay, South of Chincoteague to Duck North Carolina.
Winds in and around the area ‘could be stronger’ or weaker. It all depends on how strong Sandy Gets.: Winds as strong as but not limited to ‘Hurricane Force [74 mph to 95 mph / Category 1]’ strength will reach the Mid-Atlantic states including New York City and Long Island ‘later today’. Elevated Winds will likely be ‘Stronger’ than those near ground level. These stronger winds will affect the ‘upper floors of high rise buildings’. Stay away from the windows if you live on upper floors. Winds may also be stronger due to the funneling effect caused by buildings and other structures. Tropical Storm force winds [39 mph to 73 mph] and or Gale force Winds [39 mph to 54 mph] are already being felt from North Carolina ‘northward’ to Long Island. These winds are expected to spread to other areas of the Mid-Atlantic coast, New York City and Southern New England later this morning and today.
Storm Surge measured ‘above ground’ – It ‘could be more’ or less. It all depends on the timing [high tide/low tide] and how strong Sandy Gets. :
Long Island Sound / Paritan Bay / New York Harbor – 6 to 11 Feet
Fron Ocean City Maryland to the Connecticut / Rhode Island Border – 4 to 8 Feet
North Carolina North of Surf City including the Pamlico and Albemarle Sounds – 4 to 6 Feet
