ZCZC MIATCDAT4 ALL TTAA00 KNHC DDHHMM Tropical Depression Fourteen Discussion Number 1 NWS National Hurricane Center Miami FL AL142023 200 PM CVT Thu Sep 07 2023 Visible and infrared satellite imagery depicts that showers and thunderstorms have become better organized around a well-defined low-level center associated with the low pressure area (AL96) that NHC has been tracking the past few days. Subjective satellite Dvorak intensity estimates from TAFB and SAB were both T2.0/30 kt. Given the better defined low-level center and these satellite estimates, advisories are being initiated on Tropical Depression Fourteen over the far eastern Atlantic, with an initial intensity of 30 kt. The depression is moving generally west-northwest and this motion is forecast to continue over the next few days, with a decrease in forward speed and a turn to the north at the end of the forecast period, into a weakness in the tropical ridge. The guidance envelope is in fairly good agreement and the NHC track forecast lies between the HCCA and TVCA consensus aids. Tropical Depression Fourteen is forecast to be over warm sea surface temperatures near 28-29 degrees Celsius during the next several days. However, the depression will encounter some northerly vertical wind shear, and drier mid-level relative humidities along the current forecast track. Given the mixed environmental conditions the NHC forecast calls for gradual strengthening during the early part of the forecast but brings the system to hurricane strength before the end of the period. The NHC intensity forecast lies near the HCCA and IVCN intensity consensus aids.
