Track of TS 18L

As of 5 p.m. EDT (2100 UTC) October 27, Hurricane Sandy is located within 25 nautical miles of 30.2°N 75.2°W, about 335 mi (540 km) east-southeast of Charleston, South Carolina and about 345 mi (555 km) south of Cape Hatteras, North Carolina.

Maximum sustained winds are 65 knots (75 mph, 120 km/h), with stronger gusts. Minimum central pressure is 961 millibars (hPa; 28.38 inHg), and the system is moving northeast at 11 kt (13 mph, 20 km/h). Hurricane force winds extend up to 105 miles (165 km) from the center of Sandy, and tropical storm force winds up to 520 miles (835 km) from the center.

Sandy continues to be a large and dangerous system and poses a major threat to portions of the Mid-Atlantic and Northeast. Residents from New England to New York, Pennsylvania, New Jersey, Delaware, Maryland, Virginia and West Virginia should begin to prepare for Sandy.

Effects from Sandy could potentially begin as early as Sunday and peak in intensity Monday into Tuesday. The latest projected path takes the center of Sandy into the Northeast coast between Long Island and the Del-Mar-Va Peninsula.

Track of TY 18W

Super Typhoon Jelawat (18W) is currently churning across the Philippines Sea. Jelawat became a dangerous storm over the weekend with a perfectly symmetrical circulation and clear, well-defined eye. The storm underwent explosive intensification, almost doubling strength over the course of 12 hours.

Super Typhoon Jelawat is currently located approximately 400 nautical miles east-northeast of Manila, Philippines, having tracked northward at 4 knots over the past six hours. Maximum significant wave height is 45 feet.

Despite being hundreds of miles away from the Philippines, the system has already brought gusty thunderstorms and drenching rains to the eastern-half of the islands. As the system drifts north and eastward, it will bring the potential to bring major impacts to the islands.

While a direct landfall is not currently forecast, the system’s proximity to Luzon could still lead to serious impacts. Heavy and gusty showers and thunderstorms are expected to bombard the island for days to come. Due to the mountainous terrain of Luzon and much of the Philippines, extreme rainfall amounts, flash-flooding and mudslides are possible. Jelawat is forecast to pass east of Luzon, on a northward path generally near Taiwan.

Track of TS 18W

Tropical Storm Roke (18W), located approximately 90 nm north-northeast of Tokyo, Japan, has tracked northeastward at 31 knots over the past six hours.

Animated infrared satellite imagery indicates rapidly weakening deep convection, sheared northeast of the low-level circulation center. The bulk of the deep convection is now located over the northeast quadrant and also shows a weak frontal signature.

TS 18W is undergoing extra-tropical transition (ETT) and is forecast to complete ETT by TAU 12 as it tracks rapidly northeastward. The system will be closely monitored for signs of regeneration. Maximum significant wave height is 22 feet.
