Joaquin, unfortunately, is the real thing. NHC:
1. Preparations to protect life and property within the warning
areas in the Bahamas should be rushed to completion.
2. A significant adjustment to the forecast has been made this
afternoon, and this shows an increased threat to the mid-Atlantic
states and the Carolinas. However, confidence in the details of the
forecast after 72 hours remains low, since we have one normally
excellent model that keeps Joaquin far away from the United States
east coast. The range of possible outcomes is still large, and
includes the possibility of a major hurricane landfall in the
Carolinas.
3. Every effort is being made to provide the forecast models with
as much data as possible. The NOAA G-IV jet has begun a series of
missions in the storm environment, and the National Weather Service
is launching extra balloon soundings.
4. Because landfall, if it occurs, is still more than three days
away, it is too early to talk about specific wind, rain, or surge
impacts from Joaquin in the United States. Even if Joaquin stays
well out to sea, strong onshore winds will create minor to moderate
coastal flooding along the coasts of the mid-Atlantic and
northeastern states through the weekend.
5. A hurricane watch for a portion of the U.S. coast could be
required as early as Thursday evening.
6. Many areas of the eastern U.S. are currently experiencing heavy
rains and gusty winds associated with a frontal system. This
inclement weather is expected to continue over the next few days,
which could complicate preparations for Joaquin should it head
toward the coast, and greatly exacerbate the impacts from the
hurricane. Heavy rains are likely to continue over these areas
even if the center of Joaquin stays out to sea.
