WATCHES AND WARNINGS
--------------------
There are no coastal watches or warnings in effect.
 
Interests in the northern Leeward Islands, Virgin Islands, and
Puerto Rico should monitor the progress of this system.
 
 
DISCUSSION AND OUTLOOK
----------------------
At 900 AM AST (1300 UTC), the center of Tropical Storm Peter was 
located near latitude 17.6 North, longitude 56.0 West. Peter is 
moving toward the west-northwest near 15 mph (24 km/h) and this 
motion is expected to continue through Wednesday. On the forecast 
track, Peter is expected to pass well to the north of the northern 
Leeward Islands on Monday and Tuesday.
 
Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Some additional strengthening is forecast during the next day or
so, followed by a slow weakening trend by late Monday and on
Tuesday.
 
Tropical-storm-force winds extend outward up to 105 miles (170 km)
from the center.
 
The estimated minimum central pressure is 1008 mb (29.77 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
RAINFALL:  The outer bands south of the Tropical Storm Peter could
produce rainfall totals of 1 to 3 inches across portions of the
Northern Leeward Islands, including the Virgin Islands, as well as
Puerto Rico late Sunday into Tuesday. This rainfall may lead to
areas of urban and small stream flooding.
 
SURF:  Swells generated by Tropical Storm Peter are expected to
reach the northern Leeward Islands Sunday night and Monday.  These
swells could cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.

Tropical Storm Peter Special Discussion Number   3
NWS National Hurricane Center Miami FL       AL162021
900 AM AST Sun Sep 19 2021
 
Satellite imagery as well as data from a Air Force Reserve Hurricane
Hunter aircraft indicate that the center of Peter is over 100 n mi
west-southwest of its forecast position. Therefore, a special
advisory for track is being issued. The forecast track has been
adjusted through the first 60 h, resulting in a slight southward
adjustment of the track through the first couple of days. The
aircraft also measured 925 mb flight-level winds of 56 kt, which
supports an initial intensity of 40 kt. No adjustments were made
to the intensity forecast. The next full advisory will be issued at
1500 UTC.
 
Based on the track, intensity, and wind radii forecast, no tropical
storm watches or warnings are required for the northern Leeward
Islands, Virgin Islands or Puerto Rico.  However, interests there
should monitor the progress of the system as locally heavy rain is
possible on Monday and Tuesday when it is expected to pass to the
north of the area.
 
Key Messages:
 
1. Rainfall around the southern periphery of Tropical Storm Peter
may lead to areas of urban and small stream flooding from late
Sunday into Tuesday across Puerto Rico, the Virgin Islands, and the
Northern Leeward Islands.

The small low pressure system that the NHC has been tracking the 
past few days has acquired a well-defined circulation and enough 
organized deep convection to be classified as a tropical depression. 
The initial intensity of 30 kt is based on 0000 UTC ASCAT wind data 
of about 30 kt. This intensity is also supported by consensus Dvorak 
satellite classifications of T2.0/30 kt from TAFB and SAB.

The initial motion estimate is north-northwestward or 330/12 kt. 
The small cyclone is forecast to move in a general northwestward 
direction throughout the remainder of the forecast period as the 
system moves along the southwestern and western periphery of a 
subtropical ridge that extends westward from Africa across the Cabo 
Verde Islands. The NHC forecast track lies down the middle of the 
tightly packed track models.

Only modest strengthening is expected during the next 48 hour so 
while the small cyclone remains over 27-28 deg C sea-surface 
temperatures and the vertical wind shear decreases to near 5 kt 
during that time. However, proximity to dry air is expected 
prevent any significant strengthening from occurring. By late 
Tuesday, a slow weakening trend is forecast to begin as the system 
moves over cooler water and the shear increases from the southwest. 
The NHC intensity forecast closely follows a blend of the IVCN and 
HCCA intensity consensus models through 72 hours, and then is lower 
than the HCCA model on days 4 and 5.
