1) Eastern Pacific Hurricane Season Off to Record Early Start

Tropical Storm Adrian formed May 9, setting a new record for earliest tropical cyclone formation in the northeast Pacific in the satellite era. The previous record was held by Hurricane Alma in 1990, which developed May 12 and became a named storm May 14.

Adrian formed off the coast of southern Mexico and impacts will depend on its track, which is uncertain given that Adrian is expected to be in an area of weak steering currents by this weekend.

Heavy rain, however is likely in portions of southern Mexico and the mountains of Guatemala, which could lead to flash flooding and mudslides. If Adrian stalls off the coast, then rain may persist in the region over several days, increasing the risk of flooding.
