000 ABPZ20 KNHC 071724 TWOEP Tropical Weather Outlook NWS National Hurricane Center Miami FL 1100 AM PDT Mon Sep 7 2020 For the eastern North Pacific...east of 140 degrees west longitude: A broad area of low pressure consisting of multiple low-level swirls is located several hundred miles southwest of the southern tip of the Baja California peninsula. This system is producing only limited and disorganized showers and thunderstorms. Little or no development of the disturbance is expected for the next day or so due to strong upper-level winds. Environmental conditions are expected to become less hostile by Wednesday and some slight development is possible thereafter. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent. $$ Forecaster Zelinsky

Tropical Storm Paulette Forecast Discussion Number 3
2020-09-07 16:39:52| National Hurricane Center (Atlantic)
Issued at 1100 AM AST Mon Sep 07 2020 000 WTNT42 KNHC 071439 TCDAT2 Tropical Storm Paulette Discussion Number 3 NWS National Hurricane Center Miami FL AL172020 1100 AM AST Mon Sep 07 2020 Visible imagery and recent ASCAT data indicate that the circulation of Paulette is quite elongated from southwest to northeast. However, the ASCAT data indicated that winds up to tropical-storm-force were present, and this was corroborated by a 35 kt Dvorak-based intensity estimate from TAFB. Paulette is the 16th named storm of the 2020 Atlantic hurricane season. It is also the earliest 16th named storm of any Atlantic season by 10 days. The previous record was Philippe, which formed on September 17, 2005. Although it is elongated, the tropical storm's structure seems to have improved over the past few hours, with convection increasing in both coverage and organization. Although moderate southerly shear and some dry environmental air appear to be limiting factors, most of the intensity guidance suggests that modest strengthening is likely for the next couple of days. Near the end of the week, the models indicate that Paulette's winds will plateau or possibly decrease. This appears to be the result of increasing southwesterly shear associated with a upper-level trough that is forecast to deepen over the central Atlantic on Thursday and Friday. The official intensity forecast remains very near the multi-model consensus. Paulette has moved very little during the past few hours, but a west-northwestward to northwestward motion is expected to resume shortly. Fluctuations in the strength of a mid-level ridge over the western and central Atlantic will likely cause Paulette's exact speed and heading to fluctuate during the next several says, but the guidance agrees that it should generally head northwestward through the end of the week. It is likely that the stronger Paulette gets, the farther north it will move since the aforementioned upper-level trough will have a greater influence on its track. The NHC track forecast is based on a blend of the previous forecast and the latest multi-model consensus.
