Tropical Depression Rose Forecast Discussion Number 14

Issued at 1100 AM AST Wed Sep 22 2021 000 WTNT42 KNHC 221438 TCDAT2 Tropical Depression Rose Discussion Number 14 NWS National Hurricane Center Miami FL AL172021 1100 AM AST Wed Sep 22 2021 Rose is currently comprised of a swirl of low-level clouds with no significant convection, with an earlier burst dissipating during the last few hours. Recently received scatterometer data show 25-30 kt winds in the northeastern quadrant, so the initial intensity is held at 30 kt. The cyclone remains in an environment of northwesterly shear and upper-level convergence, and dry mid-level air has been entraining into the circulation. Since the shear is expected to increase during the next 2-3 days, the cyclone is expected to gradually weaken during this time. However, confidence in the timing of when the system will stop producing organized convection is still low. The new intensity forecast calls for Rose to degenerate into a remnant low between 60-72 h, but it is possible this could happen earlier. The initial motion is now 305/8 kt. The depression is expected to turn northward in 24-36 hours as it moves on the west side of a low- to mid-level ridge over the eastern Atlantic. By 48-60 h, a turn to the northeast is expected as Rose gets caught in the flow on the southeast side of a deep-layer trough over the north Atlantic. Based on the initial position and motion, the first 36 h of the forecast track are shifted a little to the west of the previous track. After that time, the new forecast track is similar to the previous track.

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.
