Subtropical Storm Beryl Forecast Discussion Number 17

Issued at 500 PM AST Sat Jul 14 2018 007 WTNT42 KNHC 142052 TCDAT2 Subtropical Storm Beryl Discussion Number 17 NWS National Hurricane Center Miami FL AL022018 500 PM AST Sat Jul 14 2018 While the overall coverage and intensity of convection associated with Beryl has decreased in the past few hours, the remaining convection has become better organized into a curved band. There are also indications that the center may be reforming to the north in response to this band. The initial intensity of 35 kt is based on continuity from the previous advisory and a subtropical intensity estimate of 35-40 kt from TAFB. Beryl remains embedded in an upper-level trough that is well defined in GOES-16 airmass imagery, and thus is still a subtropical cyclone rather than a tropical cyclone. The initial motion is 035/12, which is somewhat uncertain due to the possible reformation of the center. Otherwise, there is little change in the forecast philosophy from the previous advisory. Beryl is in relatively light southwesterly flow between the subtropical ridge and the mid-latitude westerlies, and this pattern should steer the cyclone generally northeastward for the next two to three days. The guidance has shifted a little to the left of that of the previous advisory, and the new forecast track is also nudged in that direction. The new track is generally a blend of the HCCA and TVCN consensus models. The intensity guidance is showing little additional development, and the new intensity forecast will reflect this in keeping the intensity at 35 kt for 24 h. However, the center of Beryl will be passing over the Gulf Stream during the next 12-18 h, so it would not surprising if some intensification occurred. After that, the system should decay over cold water with little or no extratropical transition. The new forecast now calls for dissipation before the 72 h point in agreement with the dynamical models.

Issued at 500 PM AST Sat Jul 14 2018 083 WTNT32 KNHC 142051 TCPAT2 BULLETIN Subtropical Storm Beryl Advisory Number 17 NWS National Hurricane Center Miami FL AL022018 500 PM AST Sat Jul 14 2018 ...BERYL MOVING NORTHEASTWARD WITH LITTLE CHANGE IN STRENGTH... SUMMARY OF 500 PM AST...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...37.3N 65.2W ABOUT 345 MI...555 KM N OF BERMUDA ABOUT 510 MI...820 KM S OF HALIFAX NOVA SCOTIA MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...NE OR 35 DEGREES AT 14 MPH...22 KM/H MINIMUM CENTRAL PRESSURE...1010 MB...29.83 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 500 PM AST (2100 UTC), the center of Subtropical Storm Beryl was located near latitude 37.3 North, longitude 65.2 West. The storm is moving toward the northeast near 14 mph (22 km/h) and this general motion is expected to continue through Monday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Little change in strength is forecast through Sunday. After that, Beryl should weaken as it moves over colder water, and the cyclone is expected to degenerate into a remnant low pressure area by Monday. Winds of 40 mph extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 1010 mb (29.83 inches). HAZARDS AFFECTING LAND ---------------------- None NEXT ADVISORY ------------- Next complete advisory at 1100 PM AST. $$ Forecaster Beven
