Tropical Storm Josephine Public Advisory Number 16

2020-08-15 16:32:53| National Hurricane Center (Atlantic)

Issued at 1100 AM AST Sat Aug 15 2020 000 WTNT31 KNHC 151432 TCPAT1 BULLETIN Tropical Storm Josephine Advisory Number 16 NWS National Hurricane Center Miami FL AL112020 1100 AM AST Sat Aug 15 2020 ...CENTER OF JOSEPHINE PASSING TO THE NORTHEAST OF THE LEEWARD ISLANDS... SUMMARY OF 1100 AM AST...1500 UTC...INFORMATION ----------------------------------------------- LOCATION...19.1N 60.2W ABOUT 200 MI...320 KM ENE OF THE NORTHERN LEEWARD ISLANDS MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H PRESENT MOVEMENT...WNW OR 290 DEGREES AT 16 MPH...26 KM/H MINIMUM CENTRAL PRESSURE...1008 MB...29.77 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. Interests in the Leeward Islands should monitor the progress of this system. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Tropical Storm Josephine was located near latitude 19.1 North, longitude 60.2 West. Josephine is moving toward the west-northwest near 16 mph (26 km/h), and this general motion is expected to continue for the next day or two followed by a turn toward the northwest early next week. On the forecast track, the center of Josephine is expected to pass to the northeast of the Leeward Islands today and tonight. Reports from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Little change in strength is expected through today. After that, Josephine is expected to weaken as it encounters unfavorable upper-level winds. Tropical-storm-force winds extend outward up to 80 miles (130 km) to the north of the center. The minimum central pressure estimated from the Hurricane Hunter aircraft data is 1008 mb (29.77 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Josephine is expected to cause storm-total rainfall of 1 to 3 inches over portions of the northern Leeward Islands, the Virgin Islands, and Puerto Rico. Isolated minor flooding is possible in Puerto Rico through Monday. NEXT ADVISORY ------------- Next complete advisory at 500 PM AST. $$ Forecaster Beven

Tropical Storm Josephine Forecast Discussion Number 15

2020-08-15 10:39:49| National Hurricane Center (Atlantic)

Issued at 500 AM AST Sat Aug 15 2020 000 WTNT41 KNHC 150839 TCDAT1 Tropical Storm Josephine Discussion Number 15 NWS National Hurricane Center Miami FL AL112020 500 AM AST Sat Aug 15 2020 Josephine continues to produce disorganized bursts of deep convection to the north and northeast of the estimated center, with little evidence of any banding features. In spite of the shear, the storm is still producing high-level outflow into the strong upper-level winds. The current intensity estimate of 40 kt is based on continuity from the previous scatterometer-based observations, and an ADT estimate from UW-CIMSS. An Air Force Hurricane Hunter aircraft is scheduled to investigate the storm later this morning, and this should provide a good intensity estimate. Since vertical shear associated with a large upper-level trough over the western Atlantic is forecast to become quite strong over the next few days, a weakening trend is likely to commence in a day or so. The official forecast is similar to the previous NHC prediction. It is also possible that the system will degenerate into an open wave within the next couple of days, as shown by the global models. It is difficult to locate the center at this time, but it is believed to be situated near the southwest edge of the main area of deep convection. This leads to a somewhat uncertain initial motion estimate of 300/13 kt. Josephine or its remnants are likely to continue to move west-northwestward to the south and southwest of a subtropical high pressure area, and then to turn northwest, north, and north-northeast along the periphery of the high. The official track forecast remains close to the NOAA corrected model consensus prediction. KEY MESSAGES: 1. Josephine should pass far enough to the northeast of the Leeward Islands over the weekend to prevent major impacts. However, interests there should continue to monitor its progress until the storm has passed north of that area. 2. Locally heavy rainfall is possible in the northern Leeward Islands, the Virgin Islands, and Puerto Rico as Josephine passes by to the northeast. Isolated minor flooding is possible in Puerto Rico through Monday.
