000 ABNT20 KNHC 300515 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Thu Sep 30 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Hurricane Sam, located a few hundred miles east-northeast of the northern Leeward Islands, and on Tropical Storm Victor, located over the eastern tropical Atlantic. Shower activity associated with a trough of low pressure located over the tropical Atlantic about midway between the Cabo Verde Islands and the Lesser Antilles has become limited. Environmental conditions are forecast to become less conducive over the next few days, and significant development of this system is no longer anticipated. The disturbance is forecast to move westward at 10 to 15 mph. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. && Public Advisories on Tropical Storm Victor are issued under WMO header WTNT35 KNHC and under AWIPS header MIATCPAT5. Forecast/Advisories on Tropical Storm Victor are issued under WMO header WTNT25 KNHC and under AWIPS header MIATCMAT5. $$ Forecaster Brown

Eastern North Pacific Tropical Weather Outlook
2021-09-30 07:07:24| National Hurricane Center (East Pacific)
803 ABPZ20 KNHC 300507 TWOEP Tropical Weather Outlook NWS National Hurricane Center Miami FL 1100 PM PDT Wed Sep 29 2021 For the eastern North Pacific...east of 140 degrees west longitude: A broad area of low pressure located about 1400 miles southwest of the southern tip of the Baja California peninsula is producing disorganized showers and thunderstorms. Environmental conditions are expected to be conducive for slow development during the next several days, and a tropical depression could form over the weekend or early next week while the system moves generally westward at around 10 mph. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...40 percent. Cloudiness and showers remain disorganized near a broad area of low pressure located a couple of hundred miles south-southwest of Manzanillo, Mexico. Any development of this system during the next day or two should be slow to occur while it moves toward the west-northwest at 5 to 10 mph and reaches an area of stronger upper-level winds by Friday or Friday night. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. $$ Forecaster Berg

Tropical Storm Victor Forecast Discussion Number 3
2021-09-30 04:47:28| National Hurricane Center (Atlantic)
Issued at 200 AM CVT Thu Sep 30 2021 000 WTNT45 KNHC 300247 TCDAT5 Tropical Storm Victor Discussion Number 3 NWS National Hurricane Center Miami FL AL202021 200 AM CVT Thu Sep 30 2021 Victor has changed little in organization since the last advisory, with a large circulation and a complex of convective bands mainly in the northern semicircle. Satellite intensity estimates from TAFB and SAB remain at or near 35 kt, as do other objective intensity estimates. Thus, the initial intensity is still 35 kt, although the most recent ASCAT-A data suggests the possibility that this is a little generous. The center has moved or re-formed a bit to the west during the past several hours, although the longer-term motion still seems to be to the west-northwest at 290/11 kt. Other than the more westerly initial position, there is little change to the forecast philosophy or the forecast track since the last advisory. Victor is forecast to move west-northwestward for the next 36 h or so as it is steered by the flow on the south side of a deep-layer ridge. By 48 h, the global models forecast the western periphery of the ridge to get eroded by to a mid- to upper-level low over the subtropical central Atlantic. This evolution should cause the cyclone to turn northwestward at that time, followed by a northward turn by the end of the forecast period. There remains a fair amount of spread in the timing and location of the northward turn with the GFS and HWRF still on the right side of the guidance envelope and the ECMWF showing the slowest and westernmost solution. The new forecast track is in the center of the guidance envelope and lies very close to the various consensus models. For the next 36-48 h, Victor is expected to remain in an environment of warm sea surface temperatures and light vertical wind shear. This should allow steady strengthening, and rapid strengthening cannot be ruled out if the storm develops a better defined inner core. Based on a steady strengthening scenario, the new intensity forecast is identical to the previous one, taking Victor to hurricane intensity in 36 h with a peak intensity of 70 kt in 48 h. After that time, the aforementioned upper-level low is expected to cause significant shear over Victor while the cyclone moves into a drier air mass. This combination should cause the cyclone to weaken, and it is possible Victor could weaken faster than currently forecast after 60 hours. The new official intensity forecast lies near the upper edge of the intensity guidance.
