The 2018 Atlantic hurricane season starts today (June 1) and runs through November 30. Last week (May 24, 2018) NOAA released its annual hurricane season outlook. Scientists at NOAA’s Climate Prediction Center are forecasting a 75-percent chance that the 2018 Atlantic hurricane season will be near- or above-normal.
Two of the factors driving this outlook are the possibility of a weak El Niño developing, along with near-average sea surface temperatures across the tropical Atlantic Ocean and Caribbean Sea. These factors, says the report,
.. are set upon a backdrop of atmospheric and oceanic conditions that are conducive to hurricane development and have been producing stronger Atlantic hurricane seasons since 1995.
NOAA will update the 2018 Atlantic seasonal outlook in early August, just prior to the peak of the season.

More specifically, the NOA forecasters predict a 35 percent chance of an above-normal season, a 40 percent chance of a near-normal season, and a 25 percent chance of a below-normal season for this hurricane season.
Hurricane season probability and numbers of named storms: NOAA’s forecasters predict a 70 percent likelihood of 10 to 16 named storms (winds of 39 mph or higher), of which 5 to 9 could become hurricanes (winds of 74 mph or higher), including 1 to 4 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). An average hurricane season produces 12 named storms, of which 6 become hurricanes, including 3 major hurricanes. Image via NOAA.

Bottom line: NOAA’s outlook for the 2018 Atlantic hurricane season.
