DISCUSSION AND OUTLOOK ---------------------- At 1100 AM CVT (1200 UTC), the center of Tropical Storm Rene was located near latitude 16.5 North, longitude 25.7 West. Rene is moving toward the west near 15 mph (24 km/h), and a motion toward the west to west-northwest is expected over the next few days. On the forecast track, the center of Rene will move away from the Cabo Verde Islands later tonight. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Little change in strength is expected today, followed by gradual strengthening tonight and Thursday. Rene is forecast to become a hurricane in a couple of days. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Rene can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC, and on the web at www.hurricanes.gov/text/MIATCDAT3.shtml RAINFALL: Rene is expected to produce 2 to 5 inches of rain across portions of the Cabo Verde Islands through Tuesday. WIND: Tropical storm conditions are occurring over the western portion of the Cabo Verde Islands will continue for a few more hours. SURF: Swells generated by Rene are affecting portions of the Cabo Verde Islands. These swells are likely to cause life-threatening surf and rip current conditions.

Tropical Storm Rene Forecast Discussion Number 5
2020-09-08 10:38:34| National Hurricane Center (Atlantic)
Issued at 800 AM CVT Tue Sep 08 2020 000 WTNT43 KNHC 080838 TCDAT3 Tropical Storm Rene Discussion Number 5 NWS National Hurricane Center Miami FL AL182020 800 AM CVT Tue Sep 08 2020 While Rene continues to have a well-defined circulation, satellite imagery indicates that the associated convection remains poorly organized. Various subjective and objective satellite intensity estimates are in the 30-35 kt range. Based on these, along with a 28 kt observation from Sal/GVAC, the initial intensity remains a possible generous 35 kt. The initial motion is westward or 280/13 kt. There is no change in the track forecast philosophy, as a westward motion is expected today, followed by a west-northwestward motion through Thursday as Rene rounds the southwestern periphery of a deep-layer subtropical ridge. On days 4 and 5, the cyclone is forecast to move more slowly northwestward to north-northwestward through a weakness in the aforementioned ridge. The track guidance has shifted a little eastward after 72 h, and the new track forecast is also nudged eastward during that time. Other than that, the new forecast track is similar to the previous track. It is unclear why the convection is currently so poorly organized, although land interaction with the Cabo Verde Islands is a possibility. Conditions generally appear favorable for strengthening during the next three days or so, and much of the intensity guidance forecasts Rene to become a hurricane in 2-3 days time even though the water temperatures gradually decrease along the forecast track. After 72 h, Rene is expected to reach both warmer water and strong westerly shear, with the latter expected to cause the storm to weaken. The new intensity forecast has only minor tweaks from the previous forecast and follows the trend of the intensity guidance. Key Messages: 1. Rene is expected to produce tropical storm conditions across portions of the Cabo Verde Islands today. A Tropical Storm Warning is in effect for those islands. 2. Rene will bring locally heavy rainfall to portions of the Cabo Verde Islands today.
