Subtropical Storm Beryl Forecast Discussion Number 21

2018-07-15 22:34:43| National Hurricane Center (Atlantic)

Issued at 500 PM AST Sun Jul 15 2018 763 WTNT42 KNHC 152034 TCDAT2 Subtropical Storm Beryl Discussion Number 21 NWS National Hurricane Center Miami FL AL022018 500 PM AST Sun Jul 15 2018 Beryl is less organized than 24 h ago, with the cyclone currently comprised of a swirl of low- to mid-level clouds and occasional puffs of convection in the southeastern quadrant. The low-level center has also become completely detached from a large-scale cloud band farther to the east. The initial intensity of 35 kt is based mainly on earlier scatterometer data, and this data was also used to revise the initial wind radii. Beryl has been moving slowly eastward most of the day. However, the last few satellite images suggest a more northward motion is beginning, so the initial motion is an uncertain 075/5. A broad deep-layer mid-latitude trough moving eastward across eastern Canada and the northeastern United States should cause the cyclone to turn northeastward with some acceleration tonight, with a faster northeastward motion expected on Monday and Monday night. The track guidance has shifted to the east on this advisory, so the new forecast track has been adjusted in that direction. However, the new track lies to the west of the center of the guidance envelope and the various consensus models. The new forecast track again keeps the center over the Gulf Stream for 12 h, and the intensity forecast maintains the initial intensity during that time. After that, a quick decay over cold water should occur, and the new intensity forecast now calls for Beryl to dissipate completely between 36-48 h in agreement with the dynamical guidance. The low-level center is still under strong northwesterly vertical shear, and microwave data suggests that dry air has wrapped around the circulation. If these factors prevent the quick re-development of convection, the system could dissipate even earlier than currently forecast.
