The Atlantic Hurricane Season officially runs from June 1 through November 30, but tropical systems can develop before or after those dates. Every resident in hurricane-prone areas should have a preparedness plan before the first storm threatens.

The World Meteorological Organization says it does not use “super El Niño” as an operational classification; forecasters generally classify ENSO strength by sea-surface temperature anomalies in the central-eastern equatorial Pacific, especially the Niño 3.4 region.
