Tropical Storm Laura Discussion Number 7
NWS National Hurricane Center Miami FL AL132020
1100 AM AST Fri Aug 21 2020

A NOAA Hurricane Hunter aircraft has been investigating the system
this morning and found that the maximum winds have increased to near
40 kt, and therefore the cyclone is being named. The Hurricane
Hunters also found that the center of the storm is located somewhat
to the south of previous estimates. The system is better organized
than it was yesterday, but still lacks well-defined banding
features. However, some upper-level outflow is now noted over the
southern portion of the circulation. The official forecast calls
for some slow strengthening during the next couple of days, but the
intensity forecast is quite uncertain and depends on how much
interaction with land will occur. For now, we will assume that the
northern part of the circulation will remain over water so that the
system will not be too disrupted by Hispaniola and Cuba. The
official intensity forecast remains close to the model consensus
except at days 4 and 5 where it is a little lower due to these

With the repositioning of the center, the motion is very uncertain
but is estimated to be 270/16 kt. Laura is expected to move mainly
west-northwestward on the south side of a subtropical high pressure
system over the next couple of days. Later in the forecast period,
the tropical cyclone should turn toward the northwest as it moves
around the western periphery of the high. The official track
forecast has been adjusted to the south of the previous one and is
on the northern side of the guidance suite.

Tropical storm warnings have been issued for the northern Leeward
Islands, Puerto Rico, and the Virgin Islands.

Key Messages:

1. Tropical storm conditions are expected across portions of the
northern Leeward Islands, the Virgin Islands, and Puerto Rico today
through Saturday, and Tropical Storm Warnings are in effect. Heavy
rainfall is likely across this area beginning today and could cause
mudslides and flash and urban flooding through Sunday.

2. Tropical storm conditions are possible along the northern coasts
of the Dominican Republic and Haiti, the southeastern Bahamas,
and the Turks and Caicos islands Saturday and Sunday, and Tropical
Storm Watches are in effect.

3. The details of the long-range track and intensity forecasts
remain more uncertain than usual since Laura is forecast to move
near or over portions of the Greater Antilles through Monday.
However, Laura could bring storm surge, rainfall, and wind impacts
to portions of Cuba, the Bahamas, and Florida early next week and
the northeast U.S. Gulf Coast by the middle of next week. Interests
there should monitor the progress of Laura and updates to the
forecast over the next few days.
