Remnants of Six-E Forecast Discussion Number 5

Issued at 200 PM PDT Tue Jul 14 2020 000 WTPZ41 KNHC 142037 TCDEP1 Remnants Of Six-E Discussion Number 5 NWS National Hurricane Center Miami FL EP062020 200 PM PDT Tue Jul 14 2020 A very recent ASCAT-B overpass indicated that the circulation of the tropical depression is no longer closed with light and variable winds evident on its south side. Therefore, the system no longer meets the criteria of a tropical cyclone, and this is the last advisory issued by NHC. The initial intensity remains 25 kt based on the ASCAT data, which showed an area of 20-25 kt winds on the system's north side. The remnants of the depression are currently producing a very limited amount of shower activity, but the associated convection could pulse up and down for another day until the trough moves over cooler waters. The trough is moving westward at about 15 kt and it should continue in that direction for another couple of days until it completely dissipates.

Tropical Depression Six-E Forecast Discussion Number 4
2020-07-14 16:38:36| National Hurricane Center (East Pacific)
Issued at 800 AM PDT Tue Jul 14 2020 802 WTPZ41 KNHC 141438 TCDEP1 Tropical Depression Six-E Discussion Number 4 NWS National Hurricane Center Miami FL EP062020 800 AM PDT Tue Jul 14 2020 The depression has been moving over a ridge of warmer sea surface temperatures (about 28C) over the past few hours, and a nontrivial amount of deep convection redeveloped soon after the issuance of the previous advisory, albeit at least 60 n mi to the southwest of the low-level center. However, with no appreciable change in the cyclone's structure, the initial intensity remains 25 kt in accordance with the overnight scatterometer data. The depression is forecast to reach waters colder than 26C in 12-24 hours, which should extinguish the remaining deep convection. The updated NHC forecast now shows the depression degenerating into a remnant low by 24 hours, with dissipation by 48 hours. Another scenario is that the depression could dissipate at any time if it opens up into a trough, which is shown by most of the global model guidance. The depression is moving west-northwestward, or 285/14 kt, which is more poleward than has been shown by the dynamical track models. Because of this, the simpler shallow trajectory models are given a higher contribution on this cycle, with the new NHC track forecast ending up a bit north of the previous forecast. The depression and its remnants are expected to gradually accelerate toward the west-northwest or west over the next day or two until dissipation.
