Issued at 1100 PM AST Sat Oct 02 2021 000 WTNT33 KNHC 030237 TCPAT3 BULLETIN Hurricane Sam Advisory Number 42 NWS National Hurricane Center Miami FL AL182021 1100 PM AST Sat Oct 02 2021 ...SAM GRADUALLY WEAKENING AS IT MOVES NORTHEASTWARD OVER THE OPEN ATLANTIC... SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...36.4N 57.1W ABOUT 520 MI...840 KM NE OF BERMUDA ABOUT 740 MI...1190 KM SSW OF CAPE RACE NEWFOUNDLAND MAXIMUM SUSTAINED WINDS...115 MPH...185 KM/H PRESENT MOVEMENT...NE OR 40 DEGREES AT 16 MPH...26 KM/H MINIMUM CENTRAL PRESSURE...955 MB...28.20 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Hurricane Sam was located near latitude 36.4 North, longitude 57.1 West. Sam is moving toward the northeast near 16 mph (26 km/h). This general track with an increase in forward speed is expected for the next few days. On the forecast track, Sam will move well southeast and east of Newfoundland over the North Atlantic. Maximum sustained winds are now near 115 mph (185 km/h) with higher gusts. Sam is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Further slow weakening is anticipated during the next few days, and Sam could transition into a powerful post-tropical cyclone on Monday night. Hurricane-force winds extend outward up to 70 miles (110 km) from the center and tropical-storm-force winds extend outward up to 240 miles (390 km). The estimated minimum central pressure is 955 mb (28.20 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Sam can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC, and on the web at hurricanes.gov/graphics_at3.shtml?key_messages. SURF: Swells generated by Sam will impact the northern Leeward Islands, the Greater Antilles, the Bahamas, the eastern United States and Atlantic Canada for the next couple of days. These swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Tropical Depression Victor Forecast Discussion Number 14
2021-10-02 22:40:01| National Hurricane Center (Atlantic)
Issued at 500 PM AST Sat Oct 02 2021 000 WTNT45 KNHC 022039 TCDAT5 Tropical Depression Victor Discussion Number 14 NWS National Hurricane Center Miami FL AL202021 500 PM AST Sat Oct 02 2021 Victor was about out of time as a tropical cyclone, but a recent burst of deep convection about 60 n mi northeast of its center saved it from being declared a remnant low this afternoon. The cyclone continues to struggle with dry air and strong southwesterly shear. Scatterometer overpasses missed Victor today, so the initial advisory intensity of 30 kt is based on the latest CI-value from the TAFB Dvorak estimate. The depression is moving northwest, or 310/12 kt in the flow to the southwest of a subtropical ridge. This general motion is forecast to continue until Victor dissipates in a few days. The latest NHC track forecast is little changed from the previous one, and is near the various multimodel track consensus solutions. Victor refused to succumb to the strong shear and dry air over the past 24 h. However, these hostile conditions are not forecast to abate over the cyclone for the foreseeable future. Therefore, the depression should struggle to maintain persistent deep convection, and the cyclone could degenerate to a remnant low at any time over the next couple of days. The global model guidance is in good agreement that Victor should gradually weaken early this week, and open into a tough of low pressure by Tuesday. The latest NHC intensity forecast is unchanged from the previous one, except for the timing of the system becoming a remnant low.
