Issued at 1100 PM AST Sun Jul 15 2018 530 WTNT32 KNHC 160233 TCPAT2 BULLETIN Post-Tropical Cyclone Beryl Advisory Number 22 NWS National Hurricane Center Miami FL AL022018 1100 PM AST Sun Jul 15 2018 ...BERYL BECOMES A REMNANT LOW... ...THIS IS THE LAST ADVISORY... SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...38.6N 62.4W ABOUT 455 MI...735 KM NNE OF BERMUDA ABOUT 420 MI...675 KM S OF HALIFAX NOVA SCOTIA MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...ENE OR 65 DEGREES AT 13 MPH...20 KM/H MINIMUM CENTRAL PRESSURE...1011 MB...29.86 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Post-Tropical Cyclone Beryl was located near latitude 38.6 North, longitude 62.4 West. The post-tropical cyclone is moving toward the east-northeast near 13 mph (20 km/h). A turn toward the northeast and a faster forward speed are expected tomorrow, with this motion continuing through early Tuesday. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Gradual weakening is expected during the next day or so, and the low is forecast to dissipate on Tuesday. The estimated minimum central pressure is 1011 mb (29.86 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on this system. 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 available on the Web at http://ocean.weather.gov/shtml/NFDHSFAT1.shtml. $$ Forecaster Brown

Subtropical Storm Beryl Forecast Discussion Number 21

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.
