Issued at 500 AM HST Wed Jun 24 2020 000 WTPZ43 KNHC 241457 TCDEP3 Tropical Depression Three-E Discussion Number 1 NWS National Hurricane Center Miami FL EP032020 500 AM HST Wed Jun 24 2020 The small low pressure area well southwest of the southern tip of the Baja California peninsula has acquired enough organized convection near and southwest of the center to be designated a tropical depression. Thus, advisories are being initiated on Tropical Depression 3-E. The initial intensity is set at 30 kt in agreement with satellite intensity estimates from TAFB and SAB. The initial motion is 275/6. A deep-layer ridge to the north of the cyclone is weakening as a mid- to upper-level trough develops to the northwest and west. This evolution should cause the depression to move northwestward between 24-72 h. After that, the cyclone should be weakening with the low-level trade winds becoming the main steering mechanism, resulting in a west-southwestward motion for the balance of the forecast period. The official track forecast is near the various consensus models. Conditions appear favorable for strengthening for the first 36 h or so, and the depression is expected to strengthen into a tropical storm during that time. Beyond that time, increasing vertical wind shear and dry air entrainment should cause a gradual weakening trend, and most of the global models forecast dissipation near 120 h. The forecast peak intensity of 45 kt is near the upper end of the intensity guidance, with the remainder of the forecast near the intensity consensus.
