Hurricane Jerry Forecast Discussion Number 9

2019-09-19 16:57:05| National Hurricane Center (Atlantic)

Issued at 1100 AM AST Thu Sep 19 2019 000 WTNT45 KNHC 191456 TCDAT5 Hurricane Jerry Discussion Number 9 NWS National Hurricane Center Miami FL AL102019 1100 AM AST Thu Sep 19 2019 Satellite images indicate that the center of Jerry is on the northwestern side of the central dense overcast near a very deep convective burst. An Air Force recon plane just flew through the center and found a central pressure of 988 mb and SFMR values near 65 kt. These data support making Jerry the 4th hurricane of the 2019 Atlantic hurricane season with initial wind speed of 65 kt. Jerry has the potential to further strengthen today, but an increase in northwesterly shear related to an upper-level ridge is anticipated overnight. This change in shear will likely arrest the development of Jerry and start a slow weakening trend sometime tomorrow. In 3 or 4 days, Jerry could enter a more conducive environment for strengthening, but there is a pretty large spread in the shear forecast near the cyclone at this time, related to the positioning of Jerry relative to the ridge. Since the environmental uncertainty at long range is so high, little change has been made to the previous forecast. The initial motion is estimated to be west-northwestward, or 295/14 kt. The track forecast has remained rather consistent during the past several cycles, taking Jerry just north of the Leeward Islands during the first couple of days due to seemingly reliable steering flow from the subtropical ridge to the north. The track is a little trickier beyond that time due to some dependence on the strength of Jerry, with a stronger system likely moving a bit longer toward the west-northwest, similar to the latest ECMWF/HWRF forecast. Regardless, the cyclone should eventually turn northward and northeastward by day 5 due to a substantial break in the subtropical ridge. The track forecast puts slightly greater weight on those stronger solutions, and the official track forecast is a little left of the various consensus aids and not too far from the last NHC prediction. Key Messages: 1. Although the core of Jerry is expected to pass north of northern Leeward Islands, tropical-storm-force winds and locally heavy rainfall are possible, and tropical storm watches are in effect.

On the forecast track, the center of Jerry will be near or north of the northern Leeward Islands Friday, pass north of Puerto Rico on Saturday and east of the southeastern Bahamas on Sunday. Maximum sustained winds have increased to near 75 mph (120 km/h) with higher gusts. Jerry is forecast to strengthen during the next day before some weakening begins this weekend. Hurricane-force winds extend outward up to 10 miles (20 km) from the center and tropical-storm-force winds extend outward up to 45 miles (75 km). An Air Force Reserve Hurricane Hunter aircraft recently reported a minimum central pressure of 988 mb (29.18 inches).
