Tropical Storm Enrique Forecast Discussion Number 17
2021-06-29 10:46:49| National Hurricane Center (East Pacific)
Issued at 300 AM MDT Tue Jun 29 2021 000 WTPZ45 KNHC 290846 TCDEP5 Tropical Storm Enrique Discussion Number 17 NWS National Hurricane Center Miami FL EP052021 300 AM MDT Tue Jun 29 2021 Enrique has lost most of its associated deep convection, likely due to the entrainment of drier and more stable air. Upwelling of cooler waters beneath the slow-moving circulation may also be a contributing factor. Based on data from a couple of earlier scatterometer overpasses, the intensity was reduced to 45 kt. Given the dearth of convection, this may be a generous estimate for the current intensity of the storm. Since the thermodynamic environment is not expected to become any more conducive, weakening is forecast. The official intensity forecast is similar to the previous one and close to the model consensus. It should be noted that Enrique could weaken more rapidly than expected if significant deep convection does not redevelop within the circulation soon. Therefore, the intensity forecast for this system is highly uncertain. The center has become very difficult to locate and the fixes have considerable spread, making the initial position and motion estimates quite uncertain. Based heavily on continuity, the initial motion estimate is a continued northwestward track, or 325/5 kt. The flow to the west of a mid-level ridge over northwestern Mexico should steer Enrique generally northwestward for the next couple of days, taking the system near or over the southern Baja California Peninsula. Given the uncertainty as to whether Enrique will maintain tropical storm intensity by the time it moves near or over southern Baja, it is decided to continue with a Tropical Storm Watch for that area, and not upgrade it to a warning at this time. Key Messages: 1. The outer rainbands of Enrique are likely to produce heavy rains across a portion of western Mexico and the southern Baja Peninsula during the next couple days. The additional rainfall over the mainland of Mexico will continue to pose a threat of flash flooding and mudslides. 2. Tropical-storm-force winds are possible over portions of the southern portion of the Baja California Peninsula beginning tonight, and a Tropical Storm Watch is in effect for that area. 3. Swells generated by Enrique will affect the southwestern coast of Mexico during the next day or two, and will spread northward along portions of the coast of southern Baja California Peninsula and Gulf of California during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Tropical Storm Enrique Forecast Discussion Number 16
2021-06-29 04:39:44| National Hurricane Center (East Pacific)
Issued at 900 PM MDT Mon Jun 28 2021 000 WTPZ45 KNHC 290239 TCDEP5 Tropical Storm Enrique Discussion Number 16 NWS National Hurricane Center Miami FL EP052021 900 PM MDT Mon Jun 28 2021 Deep convection associated with Enrique has continued to wane this evening, with the cloud tops warming and the center located just to the northwest of the remaining convective activity. The subjective Dvorak T-numbers from TAFB and SAB continue to decrease along with the UW/CIMSS objective T-numbers. A blend of these and an earlier SATCON estimate yields an initial wind speed of 50 kt for this advisory. Although the center of Enrique is located over SSTs of around 28C, the storm has been entraining a drier and more stable air mass located just to its west, which has led to the loss of organization. Bursts of deep convection will likely continue during the next day or so while the storm moves northwestward near a sharp SST gradient. However, steady weakening is anticipated during Enrique's approach to the southern portion of the Baja peninsula. Land interaction and decreasing SSTs should cause the system to degenerate into a remnant low in a couple of days, and dissipate within 72 hours. Enrique is moving northwestward or 320/5 kt. The track forecast reasoning is unchanged from before. A low- to mid-level ridge to the northeast of the storm should steer Enrique northwestward over the next couple of days. The track guidance has shifted back to the east this cycle and the NHC forecast has been nudged in that direction, but it lies a little to the west of the latest multi-model consensus aids. The guidance has again trended faster and the NHC forecast has been adjusted accordingly. Key Messages: 1. The outer rainbands of Enrique are likely to produce heavy rains across a portion of western Mexico and the southern Baja Peninsula during the next couple days. The rainfall over the mainland of Mexico continue to pose a threat of life-threatening flash flooding and mudslides. 2. Tropical-storm-force winds are possible over portions of the southern portion of the Baja California Peninsula beginning Tuesday night and a Tropical Storm Watch is in effect for that area. 3. Swells generated by Enrique will affect the southwestern coast of Mexico during the next day or two, and will spread northward along portions of the coast of southern Baja California Peninsula and Gulf of California during the next couple of days.

Tropical Depression Danny Forecast Discussion Number 3
2021-06-29 04:32:42| National Hurricane Center (Atlantic)
Issued at 1100 PM EDT Mon Jun 28 2021 000 WTNT44 KNHC 290232 TCDAT4 Tropical Depression Danny Discussion Number 3 NWS National Hurricane Center Miami FL AL042021 1100 PM EDT Mon Jun 28 2021 Danny made landfall just north of Hilton Head on Pritchards Island, South Carolina, around 2330 UTC with maximum winds of about 35 kt. Since then, the storm moved inland across extreme southern South Carolina and is now located over east-central Georgia. Surface observations and Doppler radar data indicate that Danny has weakened, and the cyclone has now been downgraded to a 30-kt tropical depression. Heavy rains associated with the depression are spreading westward across central Georgia. The weakening cyclone is moving west-northwestward at about 13 kt. This general motion is expected to continue overnight and Tuesday taking Danny, or its remnants, across Georgia and northern Alabama. As the system continues its trek inland, additional weakening is forecast, and Danny will likely dissipate by late Tuesday. Key Messages: 1. Heavy rainfall is possible from coastal southern South Carolina and Georgia, inland across the Piedmont of Georgia into northeast Alabama. Isolated flooding is possible across urban areas of the southern South Carolina and Georgia coasts.
