2015 Hurricane Outlook: A Tale of Two Basins:
NOAA issued the first outlook for the 2015 hurricane season, calling for a 70% likelihood of a below-normal season in the Atlantic, but a 70% chance of an above-normal season in the Eastern Pacific. Both seasons officially run from June 1 - November 30, though activity has already been observed in both basins. NOAA is predicting 6 to 11 named storms (winds of 39 mph or higher) in the Atlantic, of which 3 to 6 could become hurricanes, including 0 to 2 major hurricanes. The Eastern Pacific outlook calls for 15 to 22 named storms, of which 7 to 12 are expected to become hurricanes, including 5 to 8 major hurricanes. Both of these outlooks are dominated by effects of the strengthening El Ninõ conditions, bringing warmer than normal surface temperatures to the Eastern Pacific, and near-normal temperatures in the Western Atlantic.
