| #1148600 (Received by flhurricane at: 4:48 PM 20.Aug.2023) TCDAT2 Tropical Storm Emily Discussion Number 2 NWS National Hurricane Center Miami FL AL072023 500 PM AST Sun Aug 20 2023 Emily is feeling the effects of southwesterly vertical wind shear with the low-level center fully exposed to the southwest of the main area of deep convection. The initial intensity is held at 45 kt based on the earlier ASCAT data and the TAFB Dvorak satellite estimate. The environment around Emily is expected to become increasingly hostile the next couple of days with shear increasing to near 40 kt while the system remains in relatively stable air. These unfavorable atmospheric conditions should cause steady weakening, and Emily could become a remnant low in a few of days. The storm is moving to the northwest at 8 kt, and a general west-northwest to northwest motion is expected during the next 2 to 3 days while the storm moves along the southwestern periphery of the ridge. After that time, a turn to the north is forecast while the storm moves around the west side of the ridge and toward a weakness. The new track forecast is similar to the previous one and near the middle of the guidance envelope.
