SUMMARY OF 500 AM AST...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...38.3N 52.4W ABOUT 810 MI...1305 KM NE OF BERMUDA ABOUT 1375 MI...2215 KM W OF THE AZORES MAXIMUM SUSTAINED WINDS...75 MPH...120 KM/H PRESENT MOVEMENT...NE OR 40 DEGREES AT 25 MPH...41 KM/H MINIMUM CENTRAL PRESSURE...987 MB...29.15 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM AST (0900 UTC), the center of Hurricane Lee was located near latitude 38.3 North, longitude 52.4 West. Lee is moving toward the northeast near 25 mph (41 km/h). An acceleration toward the northeast is forecast to continue through Saturday. Maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts. Additional weakening is forecast, and Lee is expected to become a tropical storm later today. Lee will then dissipate by Saturday. Hurricane-force winds extend outward up to 40 miles (65 km) from the center, and tropical-storm-force winds extend outward up to 140 miles (220 km). The estimated minimum central pressure is 987 mb (29.15 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 1100 AM AST. $$ Forecaster Berg

Issued at 1100 PM AST Thu Sep 28 2017 000 WTNT44 KNHC 290232 TCDAT4 Hurricane Lee Discussion Number 44 NWS National Hurricane Center Miami FL AL142017 1100 PM AST Thu Sep 28 2017 Due to the 40 kt of belligerent northerly shear impinging on the northern half of the cyclone, Lee's surface circulation center has become partially exposed near the northwestern edge of the cloud canopy. A compromise of the subjective and objective Dvorak satellite T-number estimates yields a reduced initial intensity of 70 kt. Persistent strong northerly to northwesterly shear and decreasing oceanic temperatures should further weaken Lee during the next 36 hours. Afterward, the global models indicate that the system will become absorbed by a larger baroclinic system over the northern Atlantic. The official intensity forecast is similar to the previous one, and is an average of the Decay-SHIP and LGEM models. The initial motion is estimated to be northeastward, or 045/19 kt. The decaying cyclone is expected to continue accelerating toward the northeast within deep-layer mid-latitude southwesterly flow until dissipation occurs in 48 hours. The NHC forecast follows the TVCN multi-model consensus and the ECMWF closely, and is basically an update of the previous track forecast. Lee's wind radii have been adjusted based on a recent 0012 UTC ASCAT-B scatterometer overpass.
