Subtropical Storm Beryl Forecast Discussion Number 16

2018-07-14 18:50:05| National Hurricane Center (Atlantic)

Issued at 100 PM AST Sat Jul 14 2018 330 WTNT42 KNHC 141649 TCDAT2 Subtropical Storm Beryl Special Discussion Number 16 NWS National Hurricane Center Miami FL AL022018 100 PM AST Sat Jul 14 2018 The remnants of Beryl have persisted for the past several days, moving through the Bahamas and into the Atlantic between the eastern United States and Bermuda. During the last day or so, the remnants have interacted with an upper-level trough, which has resulted in the redevelopment of a well-defined circulation and organized convection near the center. Recent scatterometer data shows 35 kt winds northeast of the center, so advisories are re-initiated on Beryl. While the strongest winds and convection are relatively close to the center, the upper-level trough is likely contributing baroclinic energy to the system, and thus the regenerated Beryl is being called a subtropical cyclone rather than a tropical cyclone. The initial motion is 035/10. 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. Some increase in forward speed may occur after 36 h as a mid-latitude cyclone approaches from the west. The forecast track is a blend of the HCCA and TVCN consensus models. The forecast track takes Beryl over cold water north of the Gulf Stream in 24 h or less, and the guidance shows little additional intensification during that time. After that, the system should decay over cold water without any extratropical transition. The intensity forecast calls for the system to maintain a 35 kt intensity for 24 hr, followed by weakening and eventual dissipation just after 72 h.

DISCUSSION AND OUTLOOK ---------------------- At 100 PM AST (1700 UTC), the center of Subtropical Storm Beryl was located near latitude 36.4 North, longitude 65.7 West. The storm is moving toward the northeast near 12 mph (19 km/h) and this general motion is expected to continue through Monday. Satellite wind data indicate that 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 500 PM AST. $$ Forecaster Beven
