Extreme southern Vietnam, from near Ho Chi Minh City southward may feel the effects of the outer fringes of the storm, with gusty winds, heavy rainfall, and rough coastal conditions.
Sonamu’s maximum sustained winds had increased to near 35 knots (40.2 mph/64.8 kph). Sonamu’s center was located about 430 nautical miles (494.8 miles/ 796.4 km) east-southeast of Ho Chi Minh City, Vietnam.
Sonamu is moving to the west at 14 knots (16.1. mph/26 kph) and is expected to continue in that general direction for the next couple of days with its center staying over open waters as it passes southern Vietnam.
Joint Typhoon Warning Center (JTWC) forecasters expect that Sonamu will peak in intensity sometime on Jan. 5 and then weaken as vertical wind shear increases. Sonamu is forecast to turn to the south-southwest and make landfall early next week in east central Malaysia. Provided by NASA’s Goddard Space Flight Center
