Post-Tropical Cyclone Andrea Forecast Discussion Number 5
2019-05-21 22:33:48| National Hurricane Center (Atlantic)
Issued at 500 PM AST Tue May 21 2019 000 WTNT41 KNHC 212033 TCDAT1 Post-Tropical Cyclone Andrea Discussion Number 5 NWS National Hurricane Center Miami FL AL012019 500 PM AST Tue May 21 2019 The cyclone has lacked deep convection since early this morning, and therefore it no longer qualifies as either a tropical or a subtropical cyclone. Dry mid-level air, the influence of an upper-level low, and marginal SSTs should preclude re-development. The cyclone is likely to dissipate in a day or so as it becomes absorbed into a frontal zone. Post-tropical Andrea has turned to the east-northeast and the motion is about 070/7. The system should move mainly eastward within the mid-level westerlies until dissipation. This is the last advisory on Andrea. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online at ocean.weather.gov/shtml/NFDHSFAT1.php FORECAST POSITIONS AND MAX WINDS INIT 21/2100Z 30.8N 68.3W 30 KT 35 MPH...POST-TROPICAL 12H 22/0600Z 31.2N 67.0W 30 KT 35 MPH...POST-TROP/REMNT LOW 24H 22/1800Z 31.7N 62.8W 25 KT 30 MPH...POST-TROP/REMNT LOW 36H 23/0600Z...DISSIPATED $$ Forecaster Pasch

Subtropical Depression Andrea Forecast Discussion Number 4
2019-05-21 16:35:44| National Hurricane Center (Atlantic)
Issued at 1100 AM AST Tue May 21 2019 000 WTNT41 KNHC 211435 TCDAT1 Subtropical Depression Andrea Discussion Number 4 NWS National Hurricane Center Miami FL AL012019 1100 AM AST Tue May 21 2019 As expected, Andrea is likely to be a short-lived event. The cyclone's cloud pattern has continued to degrade, and Andrea is now essentially devoid of deep convection. In fact, at first glance, the upper-level low to the southwest of the center appears to be the most dominant feature. Based on the lack of convection and a buoy observation not far to the north of Andrea, the system is being downgraded to a subtropical depression. Since the cyclone is expected to remain under the influence of the upper low and in and environment of dry mid-level air for the next day or so, Andrea is likely to degenerate into a remnant low pressure area in a day or less. The system has moved a little more to the north than previously estimated and the initial motion is 360/7. Upper-level westerlies should cause the cyclone to turn eastward in 12-24 hours until dissipation. The official track forecast is similar to but a little slower than the dynamical model consensus, TVCN.

Subtropical Storm Andrea Forecast Discussion Number 3
2019-05-21 10:35:39| National Hurricane Center (Atlantic)
Issued at 500 AM AST Tue May 21 2019 000 WTNT41 KNHC 210835 TCDAT1 Subtropical Storm Andrea Discussion Number 3 NWS National Hurricane Center Miami FL AL012019 500 AM AST Tue May 21 2019 During the past few hours, deep convection has waned considerably, likely due to the entrainment of dry mid-level from the south and modest southerly vertical wind shear as indciated by GOES-16 mid- and upper-level water vapor imagery. As mentioned in the previous advisory discussion, an earlier ASCAT overpass just barely caught 35-kt winds about 50-55 nmi northeast of the low-level center, which was likely just outside the radius of maximum winds. Since slightly stronger winds could have existed closer to the center, the initial intensity is being maintained at 35 kt for this advisory despite the aforementioned degradation in the convective pattern. The initial motion estimate is 360/05 kt. It appears that Andrea is slowing down, implying that a turn toward the northeast should occur within the next 6-12 h as a deep-layer trough and cold front steadily approach the cyclone from the northwest. The global and regional models remain in good agreement that Andrea will turn northeastward later today, and then move eastward by tonight and Wednesday when the cyclone becomes embedded within the approaching deep-layer mid-latitude westerly flow. The NHC track forecast is essentially unchanged from the previous advisory and lies a little south of the middle of the track guidance envelope. Although deep convection has decreased markedly, thunderstorm activity should redevelop some by this afternoon and tonight when Andrea will be moving eastward over an SST thermal ridge and into a region of convective instability that exist between 65W-68W longitude. which will also be coincident with the vertical wind shear decreasing to less than 5 kt as per SHIPS model output. However, some slight spin down of the vortex will likely occur before convection can re-fire and re-strengthens the system. Thus, the intensity forecast essentially calls for little change in strength for the next 24 h or so, followed by weakening due to increasing northwesterly vertical wind shear, and then merger with a cold front on Wednesday. The official intensity forecast closely follows the IVCN consensus model and the weakening trend noted in the global models.

Subtropical Storm Andrea Forecast Discussion Number 2
2019-05-21 04:32:09| National Hurricane Center (Atlantic)
Issued at 1100 PM AST Mon May 20 2019 000 WTNT41 KNHC 210231 TCDAT1 Subtropical Storm Andrea Discussion Number 2 NWS National Hurricane Center Miami FL AL012019 1100 PM AST Mon May 20 2019 There has not been much change in association with Andrea since the previous advisory a few hours ago. Satellite images show a persistent area of deep convection that is mainly confined to the north of the center, with less organized convection wrapping around to the southeastern quadrant. A recent partial ASCAT pass showed maximum winds of 35 kt, which is similar to what the aircraft found earlier this evening and in about the same location. Therefore, the initial intensity is held at 35 kt. This estimate is also in agreement with the latest satellite intensity consensus from CIMSS at the University of Wisconsin. Andrea is located a few hundred miles from a mid- to upper-level low, and its interaction with this feature is part of the reason why the cyclone is considered subtropical. This upper low and a ridge to the east is causing Andrea to move northward at about 10 kt. The models are in good agreement that Andrea should slow down and turn northeastward on Tuesday, and then eastward Tuesday night and Wednesday when it becomes embedded in the mid-latitude westerlies. The NHC track forecast is very similar to the previous one and lies near the middle of the model guidance. Andrea could strengthen slightly overnight while it remains in a relatively moist and unstable atmosphere. However, after that time, a gradual weakening trend is predicted due to less favorable environmental conditions. All of the reliable models agree that Andrea will merge with, or be absorbed by, a cold front on Wednesday. This intensity forecast is in best agreement with the GFS model.
