High Quality Content by WIKIPEDIA articles! Tropical Storm Blanca was a short-lived tropical cyclone during the 2009 Pacific hurricane season. Forming out of a trough of low pressure on July 6, Blanca was immediately classified a tropical storm roughly 420 mi (675 km) south-southwest of the southern tip of the Baja California Peninsula. Later that day, the storm reached its peak intensity with winds of 50 mph (85 km/h) and a barometric pressure of 998 mbar (hPa; 29.47 inHg) as deep convection persisted around the center of circulation. Shortly after, the system began to weaken. Intermittent bursts of convection occurred on July 7 before Blanca weakened to a tropical depression. The following day, the system degenerated into a remnant low pressure system, devoid of shower and thunderstorms. The remnants were monitored by the National Hurricane Center for another day. Although the storm did not impact land as a tropical cyclone, its remnants produced unseasonable rains in southern California and moisture from the system contributed to flooding in Mexico.
