ContactRelief Recommendations for Florida, Georgia, South Carolina, and North Carolina

ContactRelief has issued a Tropical Weather Strategy alert and recommendation for parts of Florida, Georgia, South Carolina, and North Carolina. Our current recommendation is to suspend non-essential contact.  An extension of this recommendation may be required in certain heavily hit areas if the storm makes landfall. In areas with no damage or less damage, contact may be resumed early after the storm passes.

Dorian is a catastrophic hurricane at Category 5 strength.  Dorian is expected to approach the Florida coastline on Tuesday.  The storm is now predicted to track offshore of the southeastern coastline from Florida to North Carolina. However, the track is still uncertain and as a major hurricane, coastal areas will be severely impacted even if the storm fails to make landfall.  We are holding the recommended suspension area constant until the track stabilizes.

Residents are actively preparing for the upcoming storm.  As the storm nears landfall, these preparations will intensify further.  You can promote and protect your brand image implementing a proactive customer care policy now.  You should consider messaging opportunities before and after the storm, suspension of non-essential contact, financial relief programs or other services, creating specialized IVRs and trained agent groups to handle interaction with disaster victims, and routing calls based on the caller's location.

National Hurricane Center Forecast Discussion

Air Force and NOAA reconnaissance planes penetrated the distinct
eye of Dorian, and found that the hurricane has become extremely
intense with a stadium effect in the eye. The NOAA plane reported a
peak flight-level wind of 159 kt, while the SFMR from both planes
have measured winds between 155 and 170 kt.  A dropsonde from the
NOAA plane measured a wind gust of 176 kt at the surface. A blend of
these measurements yield to an initial intensity of 155 kt, making
Dorian the strongest hurricane on record in the northwestern
Bahamas.

For the next few days, Dorian should experience some fluctuations in
intensity, and in addition to eyewall replacement cyclone, the
interaction with the northwestern Bahamas should weaken the
hurricane slightly. After 3 days, as Dorian moves northward along
or offshore of southeast United States coast, the shear is forecast
to increase, resulting in a more distinct gradual weakening.

Reconnaissance plane and satellite fixes indicate that Dorian, as
anticipated, has slowed down and is moving toward the west or 270
degrees at 6 kt. The steering currents are collapsing and Dorian is
expected to slow down even more, prolonging its catastrophic effects
in the northwestern Bahamas. The NHC forecast calls for a slow west
to west-northwest motion during the next 48 hours, with a turn to
the north and an increase in forward speed as the mid-level trough
along the eastern United States deepens and becomes the dominant
steering feature. The current forecast is only a few miles west of
the previous one and is basically on top of the multi-model
consensus. Both the deterministic and consensus tracks have shown
the usual variability to the right or to the left from run to run,
but the overall trend is for the hurricane to turn northward
offshore but very close to the Florida peninsula.

Given the uncertainty in the track forecast and the anticipated
increase in size of the hurricane, a Hurricane Watch and Storm
Surge Watch have been issued for a portion of the east Florida
coast. It is emphasized that although the official track forecast
does not show landfall, users should not focus on the exact track. A
small deviation to the left of the track could bring the intense
core of the hurricane its dangerous winds closer to or onto the
coast.

Key Messages:

1. A prolonged period of catastrophic winds and storm surge will
affect the Abaco Islands today. Everyone there should take immediate
shelter and not venture into the eye. These catastrophic conditions
are likely on Grand Bahama Island later today or tonight, and
efforts to protect life and property there should be rushed to
completion.

2. Storm surge and hurricane watches and tropical storm warnings are
in effect for portions of the Florida east coast. Life-threatening
storm surge and dangerous hurricane-force winds are possible along
portions of the Florida east coast through mid-week, as only a
slight deviation to the left of the official forecast would bring
the core of Dorian near or over the coast. Residents should listen
to advice given by local emergency officials.

3. There is an increasing likelihood of strong winds and dangerous
storm surge along the coasts of Georgia, South Carolina, and North
Carolina later this week. Residents in these areas should continue
to monitor the progress of Dorian.

4. Heavy rains, capable of producing life-threatening flash floods,
are possible over northern portions of the Bahamas and coastal
sections of the southeast and lower mid-Atlantic regions of the
United States through late this week.
