Tropical Depression Polo Forecast Discussion Number 8
2020-11-19 15:33:43| National Hurricane Center (East Pacific)
Issued at 700 AM PST Thu Nov 19 2020 000 WTPZ41 KNHC 191433 TCDEP1 Tropical Depression Polo Discussion Number 8 NWS National Hurricane Center Miami FL EP212020 700 AM PST Thu Nov 19 2020 Occasional bursts of deep convection have been developing to the east and northeast of Polo's center since yesterday evening, but none have lasted for more than about an hour or two. ASCAT-C data received after the scatterometer pass noted in the previous advisory did not explicitly show tropical-storm-force winds, suggesting that Polo continues to weaken, and the most recent Dvorak CI numbers from TAFB and SAB are 2.0. For these reasons, Polo is now assumed to be a 30-kt tropical depression. Polo has not maintained enough organized convection to be considered a tropical cyclone for the last 12 to 15 hours, and if sustained convection does not redevelop soon, the system will likely be declared a remnant low later this afternoon. The remnant low is expected to continue weakening due to westerly shear, only marginally warm waters, and dry air, and it is expected to dissipate by 48 hours, if not sooner. Polo is being steered westward (275/10 kt) to the south of a low- to mid-level ridge. Once Polo becomes a remnant low, the shallow circulation should take on a south-of-due-west motion in about 24 hours, continuing that trajectory until it dissipates. This pattern is shown by nearly all the reliable track models, and the NHC forecast lies down the middle of the guidance envelope.
