El Nino provides reasoning for irregularity in weather patterns across the United States. Events such as droughts and flooding can all be traced back to this one event. Normally the greatest direct impact is more precipitation for Southern California and through the southern tier of the United States. This may also help with drought stricken areas in the South-Central United states this summer, but the largest effects are felt during the winter. During the winter, wet weather likely will continue for California to the U.S Gulf Coast and Florida, while drier than average conditions will be experienced over the Pacific Northwest and the Ohio Valley.
While an El Nino is in the Pacific Ocean its effects can also be felt throughout the Atlantic, especially during hurricane season. During an El Nino season there is a notable decline in both the frequency and strength of hurricanes in the Atlantic Ocean compared to a typical hurricane season.
