'Twin Troublemaker' Saola and Typhoon Damrey Move Closer to China

Typhoon Damrey and Tropical Storm Saola continued to close in on China Thursday, as seen in the latest image released by NASA Goddard's MODIS Rapid Response Team.

Damrey, though smaller, possesses the strongest winds, winds strong enough to be hurricane force, according to the Saffir-Simpson wind scale on the U.S. National Hurricane Center's website.

Damrey is picking up strength and possesses stronger winds than Saola, according to NASA.

The U.S. Navy's Joint Typhoon Warning Center (JTWC) reported Damrey had sustained winds of 140 kilometers per hour and gusts up to 165 kilometers per hour, according to NASA. The Saffir-Simpson scale classifies winds from 119-153 kilometers per hour as Category I hurricane force winds.

NASA also reported Damrey has a distinct eye.

JTWC also reported Saola had maximum sustained winds of 85 kilometers per hour and gusts up to 100 kilometers per hour.

The JTWC's projected storm tracks show both Saola and Damrey making landfall in southeastern China on Friday, with Damrey hitting first, north of Shanghai and Saola hitting about 12 hours later, south of Shanghai, according to NASA.
