Tropical Storm Rene Forecast Discussion Number 20
2020-09-12 04:41:44| National Hurricane Center (Atlantic)
Issued at 1100 PM AST Fri Sep 11 2020 000 WTNT43 KNHC 120241 TCDAT3 Tropical Storm Rene Discussion Number 20 NWS National Hurricane Center Miami FL AL182020 1100 PM AST Fri Sep 11 2020 Deep convection has persisted near the center of Rene since this afternoon and a couple of earlier microwave overpasses suggest that there has been an increase in banding over the southwestern portion of the circulation. Despite what appears to be an increase in organization, recent ASCAT data indicated that this has not translated into an increase in intensity. The scatterometer data still supports an initial wind speed of 35 kt. Environmental conditions are forecast to generally be conducive for some strengthening over the next 12-24 hours, however with Rene continuing to struggle to intensify the NHC wind speed prediction has again been reduced during the that time. By 36-48 hours, Rene is expected to move beneath an area of strong upper-level west-northwesterly flow, and this increase in shear is expected to cause weakening. The ECMWF and GFS models significantly weaken Rene after 72 hours, with the ECMWF showing dissipation before the end of the forecast period. For now, the official forecast calls for Rene to weaken to a tropical depression by day 4, but it is possible that the system will degenerate into a trough of low pressure before day 5. Rene is moving west-northwestward or 295/12 kt. The cyclone should turn toward the northwest as it moves around the western portion of a mid-level ridge over the eastern Atlantic. In a couple of days, a mid-level high is predicted to build to the northwest of Rene, which should cause the cyclone to slow down and turn westward, and then west-southwestward later in the forecast period. The track guidance is in fairly good agreement and the various consensus aids remained close to the previous official forecast. Therefore, the new NHC forecast is essentially an update of the previous advisory.

SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...21.4N 42.4W ABOUT 1260 MI...2025 KM WNW OF THE CABO VERDE ISLANDS ABOUT 1360 MI...2190 KM ENE OF THE NORTHERN LEEWARD ISLANDS MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...WNW OR 295 DEGREES AT 14 MPH...22 KM/H MINIMUM CENTRAL PRESSURE...1004 MB...29.65 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Tropical Storm Rene was located near latitude 21.4 North, longitude 42.4 West. Rene is moving toward the west-northwest near 14 mph (22 km/h). A turn toward the northwest followed by a slower north-northwest motion is expected over the next couple of days. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some slight strengthening is forecast during the next day or so, but a weakening trend will likely begin by late Sunday. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 500 AM AST. $$ Forecaster Brown
