Tropical Depression 13 has strengthened and organized into Tropical Storm Lorenzo.
Lorenzo is forecast to become a hurricane as it moves over open Atlantic waters over the next 5 days. It’s too early to say for sure if Lorenzo will have any direct impacts on land, but typically storms that form this far east swing away from the U.S. and remain in open waters.

000 WTNT43 KNHC 231446 TCDAT3 Tropical Storm Lorenzo Discussion Number 3 NWS National Hurricane Center Miami FL AL132019 1100 AM AST Mon Sep 23 2019 Yet another tropical storm has formed over the Atlantic, this one over the far eastern portion of the basin. The system has been designated as Tropical Storm Lorenzo based on satellite intensity estimates from TAFB, SAB, and UW-CIMSS, all of which support tropical-storm strength. The initial intensity is set at 35 kt, but its possible this is somewhat conservative since the TAFB classification was a little higher. Recent GMI microwave imagery and ASCAT-C data showed that the low-level center of Lorenzo is on the north side of most of its deep convection. While this disorganized structure may limit how quickly Lorenzo can strengthen in the short-term, the tropical storm is located within a generally favorable environment for intensification. All of the intensity guidance shows Lorenzo becoming a hurricane, but the timing varies from model to model. The official forecast follows the HFIP Corrected Consensus, and shows Lorenzo reaching hurricane status within 48 h. Continued strengthening is forecast thereafter. No noteworthy changes were made to the NHC intensity forecast. The ASCAT and microwave data were very helpful in determining the location of Lorenzo's center and its forward speed. The cyclone has accelerated and the initial motion estimate is now 275/15 kt. Very little adjustment was made to the NHC track forecast. Lorenzo is still forecast to be steered generally westward to west-northwestward to the south of a deep-layer ridge centered over the eastern Atlantic. The cyclone will pass well south and southwest of the Cabo Verde Islands through tonight. A turn toward the northwest is forecast in about 4 days as Lorenzo reaches a break in the ridge. Just like the intensity forecast, the track forecast is based heavily on HCCA.
