"Preparing for La Niña: Impact on Hurricane Season and California Weather"

La Niña is expected to form this year, with a 62% chance of developing during the upcoming summer months, potentially worsening the Atlantic hurricane season by weakening wind shear and increasing storm activity. While its impact on U.S. summer weather is minimal, La Niña typically brings cold and snow to the Northwest and dry conditions to the southern tier during winter, with warmer temperatures in the Southeast and mid-Atlantic. The recent strong El Niño is weakening and expected to transition to "ENSO-neutral" conditions, with the entire El Niño/La Niña cycle known to affect weather in the U.S. and around the world.
