The cyclone is getting better organized on its approach to the Cabo Verde Islands. Banding features are now well established over the western part of the circulation, and some smaller bands are filling in east of the center. The satellite intensity estimates currently range from 30 to 35 kt. Based on this data and the improved satellite appearance of the system, the initial intensity is raised to 35 kt, making the cyclone Tropical Storm Rene. Rene is the 17th named storm of the 2020 Atlantic hurricane season. It is also the earliest 17th named storm of any Atlantic season by 11 days. The previous record was Rita, which formed on September 18, 2005.

Rene is moving west-northwestward at 10 kt, and it should continue moving in that direction with some increase in forward speed for at least the next few days while subtropical ridging builds westward to the north of the storm. Toward the end of the forecast period, a turn to the northwest is expected as Rene moves into a weakness in the ridge. The models have shifted eastward at the longer ranges, especially the ECMWF model, and the NHC forecast has been adjusted in that direction at days 3 through 5.

Rene is forecast to gradually strengthen during the next few days as the storm is expected to remain over relatively warm water while moving through an environment consisting of low vertical wind shear and high amounts of moisture. An increase in southwesterly shear late this week and this weekend should end the strengthening trend and induce some weakening. The NHC intensity forecast is again an update of the previous one and is now in line with the HCCA and IVCN consensus models.
