Issued at 1000 PM CDT Sat Sep 05 2020 000 WTPZ45 KNHC 060251 TCDEP5 Tropical Storm Julio Discussion Number 2 NWS National Hurricane Center Miami FL EP152020 1000 PM CDT Sat Sep 05 2020 Satellite imagery, including recently received microwave overpasses, shows that Julio has changed little in organization during the past several hours, with the small low-level circulation center is located near the eastern edge of the small area of central convection. The initial intensity remains 35 kt based on continuity and a satellite intensity estimated from TAFB. The initial motion is west-northwestward or 295/15 kt. The latest global models runs continue to have trouble resolving Julio, but overall the cyclone is embedded in an east-southeasterly flow on the southwest side of a mid-level ridge. A general west- northwestward motion should continue with a decrease in forward speed until the system dissipates. The new forecast track again leans more toward the ECMWF model, which does the best job of resolving Julio. The tropical storm will be affected by moderate to strong easterly wind shear for the next day or two, and only sight strengthening is likely during that time. While the shear is forecast to diminish after 24-36 h, the cyclone will encounter a drier and more stable air mass at that time, which should lead to the dissipation of the small system. The new intensity forecast is unchanged from the previous forecast, and it lies below the intensity consensus.
