Large swaths of the North Atlantic are well above normal temperature (orange and red) for this time of year, a trend that could affect the forthcoming hurricane season.


In the past few weeks, sea-surface temperatures in some parts of the North Atlantic Ocean have soared to record heights.

The anomalous warming is occurring in a large swath stretching almost one-third of the way across the Atlantic westward from the northwestern coast of Africa.
