Tropical Storms Blas and Celia were relatively close to each other in late June 2010. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite observed both storms in a single overpass on June 19, 2010. Both storms were expected to follow westward tracks over the eastern Pacific Ocean. Blas appears in the west, and Celia appears in the east, closer to Central America.
On June 20, 2010, the U.S. Navy’s Joint Typhoon Warning Center (JTWC) reported that Tropical Storm Blas had maximum sustained winds of 30 knots (55 kilometers per hour) and gusts up to 40 knots (75 kilometers per hour), having dissipated slightly over the previous two days. The JTWC reported that Tropical Storm Celia, the newer storm, was stronger, with maximum sustained winds of 65 knots (120 kilometers per hour) and gusts up to 80 knots (150 kilometers per hour).
