The first hurricane of the 2016 Atlantic season formed four and a half months before hurricane season officially begins.
As of Thursday morning, the first hurricane of the season is a Category 1 storm spinning several hundred miles south of the Azores–a sparsely populated island chain 890 miles west of Portugal. Hurricane warnings are in effect for the islands as the storm treks northward.
Hurricanes rely on warm water to form and strengthen. This storm is unusual not only because of the month in which it formed, but also because the ocean water underneath is a cool 68ºF — as brisk as Barton Springs!
Water temperatures that chilly typically cannot energize a system to hurricane strength (74+ mph). The National Hurricane Center cites an unusually unstable atmosphere within the storm environment as the reason it intensified regardless.
Hurricane Alex is expected to maintain hurricane strength for the next 24 hours, then weaken as it transitions from a tropical system to a “post-tropical” storm. That type of storm is much more common so far north in the Atlantic.
