Tropical Depression Peter Forecast Discussion Number 15
2021-09-22 10:40:30| National Hurricane Center (Atlantic)
Issued at 500 AM AST Wed Sep 22 2021 000 WTNT41 KNHC 220840 TCDAT1 Tropical Depression Peter Discussion Number 15 NWS National Hurricane Center Miami FL AL162021 500 AM AST Wed Sep 22 2021 Peter is a disorganized tropical depression. The low-level center is fully exposed and currently located a couple of hundred miles north of Puerto Rico. Most of the associated thunderstorm activity remains displaced well east of the center due to about 30 kt of westerly shear. The initial intensity is held at 30 kt based on a 0206 UTC ASCAT-B pass that showed a swath of 25-30 kt winds about 60 n mi north of the center. The ASCAT data also showed that the circulation has become quite elongated. Since the hostile conditions of strong westerly shear and dry air entrainment are not expected to let up, a continued gradual decay of Peter is forecast. The system is still predicted to become a remnant low in 36 hours and dissipate in a few days, but both of these could occur sooner. The depression is moving northwestward, with the latest initial motion estimated to be 310/10 kt. The cyclone is expected to turn northward by tonight and then northeastward by the end of the week as the system moves in the flow on the east side of a deep-layer trough. The NHC track forecast is a little to the east of the previous one and close to an average of the GFS and ECMWF models. Key Messages: 1. Rainfall around the southern periphery of Peter may lead to areas of urban and small stream flooding through Thursday morning across northern Hispaniola, Puerto Rico, and portions of the Virgin Islands.

SUMMARY OF 500 AM AST...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...21.5N 66.1W ABOUT 215 MI...345 KM N OF SAN JUAN PUERTO RICO MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...NW OR 310 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...1008 MB...29.77 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the center of Tropical Depression Peter was located near latitude 21.5 North, longitude 66.1 West. The depression is moving toward the northwest near 12 mph (19 km/h). A turn to the north is expected by tonight, followed by a north-northeastward or northeastward motion through the end of the week. On the forecast track, the center of Peter will continue moving away from the Virgin Islands and Puerto Rico. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Some gradual weakening is expected during the next couple of days, and Peter is forecast to degenerate into a remnant low on Thursday. The estimated minimum central pressure is 1008 mb (29.77 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Rainfall around the southern periphery of Peter could produce additional rainfall totals of 1 to 2 inches, with storm total accumulations up to 9 inches, across portions of the Virgin Islands, Puerto Rico, and northern portions of Hispaniola through Thursday morning. This rainfall may lead to areas of urban and small stream flooding. SURF: Swells generated by Peter are affecting the Virgin Islands, Puerto Rico, and Hispaniola, and will continue spreading westward to the Bahamas later today. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 1100 AM AST. $$ Forecaster Cangialosi

Tropical Depression Rose Forecast Discussion Number 13
2021-09-22 10:33:24| National Hurricane Center (Atlantic)
Issued at 500 AM AST Wed Sep 22 2021 000 WTNT42 KNHC 220833 TCDAT2 Tropical Depression Rose Discussion Number 13 NWS National Hurricane Center Miami FL AL172021 500 AM AST Wed Sep 22 2021 Rose remains a strongly sheared and poorly organized tropical depression. The low-level center is fully exposed and only a small area of thunderstorms is lingering on the system's east side. The initial intensity is held at 30 kt based on the latest Dvorak estimates. The cyclone is currently in an environment of about 20 kt of northwesterly shear, and dry mid-level air has been entraining into the circulation. Since the shear is expected to increase during the next few days, little change in strength or gradual weakening seems likely. Rose is forecast to become a remnant low by 60 hours when the shear is expected to be near 30 kt, but confidence in the timing of when the system will lose organized convection is low. Some of the models show Rose opening into a trough toward the end of the forecast period, but there are some solutions that hold on to the system for a while longer. The depression is moving northwestward at 7 kt. The system is expected to turn northward in about 36 hours as it moves on the west side of a low- to mid-level ridge. On Friday, a turn to the northeast is expected as Rose gets caught in the flow on the southeast side of a deep-layer trough. The models are in good agreement, and the new NHC track forecast is largely an update of the previous one.
