2015 Hurricane Outlook: A Tale of Two Basins

2015 Hurricane Outlook: A Tale of Two Basins

NOAA issued the first outlook for 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 a 6 to 11 named storms (winds of 39 mph or higher) in the Atlantic, of which 3- 6 could become hurricanes, including 0-2 major hurricanes. The Eastern Pacific outlook calls for 15-22 named storms, of which 7-12 are expected to become hurricanes, including 5-8 major hurricanes. Both of these outlooks are dominated by effects of the strengthening El Nin õ conditions, bringing warmer than normal surface temperatures to the Eastern Pacific, and near-normal temperatures in the Western Atlantic. This image from NOAA View shows the sea surface temperature departure for the week of May 18-24, 2015. Areas colored red are warmer than the 1981-2010 average; areas colored blue are cooler. The sea surface temperature data in the NOAA View updates each week - check back as the hurricane season progresses to monitor ocean temperatures.
