August 19, 2014 - Tropical Storm Karina (11E) in the eastern Pacific Ocean
Tweet
Karina was clinging to hurricane status on August 14 at 2:40 p.m. EDT (1820 UTC) when the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite passed overhead and captured this true-color image. At that time, the bulk of Karin’s clouds were being pushed to the western side of the storm – an indication that moderately strong vertical wind shear was weakening the storm.
On August 15, Karina continued to experience 20 to 25 knots of easterly vertical wind shear, which has caused the center to become partly exposed on the eastern side of the deep convection (rising air that forms the thunderstorms that make up the tropical storm).
A tropical storm has maximum sustained wind speed between 39 and 73 mph. By 5 a.m. EDT (0900 UTC) on August 15, Karina's maximum sustained winds had decreased to 70 mph (110 km/h). Karina's center was located latitude 17.2 north and longitude 119.1 west, about 715 miles (1,150 km) west-southwest of the southern tip of Baja California, Mexico. Karina was moving toward the west near 12 mph (19 km/h) and was expected to turn to the west-northwest, away from land.
On the afternoon of August 18, according to the National Hurricane Center (NHC), Karina made a little bit of a comeback, with the center embedded within deep convection. The storm has an opportunity to strengthen a little more, as it heads over warmer water and faces weaker shear for the next day or so. However, the NHC expects the outflow from larger Tropical Depression 12-E, located to the northeast, to induce stronger shear and prevent the storm from additional strengthening as it continues to move out to sea.
