Tropical Cyclone 18L (Sam)
SAM SLIGHTLY RE-STRENGTHENS OVER THE GULF STREAM…EXPECTED TO BECOME POST-TROPICAL BY EARLY TUESDAY
According to the NHC Advisory 46…Sam is moving toward the northeast near 20 mph (31 km/h). A northeastward motion at a faster forward speed is expected over the next couple of days. The cyclone is forecast to slow down over the far north Atlantic southwest of Iceland around midweek. Satellite images indicate that maximum sustained winds have increased to near 105 mph (165 km/h) with higher gusts. Gradual weakening is forecast during the next few days, and Sam is expected to transition into a powerful post-tropical cyclone by early Tuesday. 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).
HAZARDS AFFECTING LAND
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.
Tropical Cyclone 20L (Victor)
VICTOR NO VICTOR IN ITS BATTLE AGAINST DRY AIR AND SHEAR

The system is forecast to move northwestward or west-northwestward at a slightly faster forward speed through Monday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Weakening is forecast. Victor is expected to become a remnant low on Monday and will likely dissipate shortly thereafter.
