Tropical Storm Bertha Special Discussion Number 1
NWS National Hurricane Center Miami FL AL022020
830 AM EDT Wed May 27 2020

The area of disturbed weather that NHC has been tracking over the
past day or so has quickly become better organized this morning.
The circulation has become better defined and the center has
reformed beneath the area of deep convection just offshore of the
coast of South Carolina. Recent NWS Doppler radar data from
Charleston and buoy data indicates that the system is producing
tropical-storm-force winds. Therefore, advisories are being
initiated on Tropical Storm Bertha. The system will be moving
inland very shortly and little, if any, additional strengthening is
expected. Once inland, the small tropical cyclone should weaken
rapidly and dissipated over central North Carolina on Thursday.

There is very little continuity on the initial motion since the
center has only recently formed. The best estimate of the initial
motion is 320/8 kt. The system should continue to move generally
northwestward around the western side of a mid-level ridge located
over the western Atlantic. The track guidance is in good agreement
on this scenario, and the NHC track forecast is close to a blend of
the GFS and ECMWF models.

Key Messages:

1. Bertha is expected to produce heavy rainfall across portions of
eastern and central South Carolina, west-central to far
southeastern North Carolina, and southwest Virginia. This rainfall
may produce life-threatening flash flooding.

2. Bertha is expected to bring tropical storm winds to portions of
the South Carolina coast within the warning area in the next few
hours.
