Atlantic Coast Told to Expect Major Hurricanes This Season

The government’s weather center has forecast that this year’s Atlantic hurricane season that began June 1 will be an active one, perhaps even extremely active, during its six months.

Experts at the National Oceanographic and Atmospheric Administration (NOAA) said there is a 70 percent likelihood of 13 to 20 named storms (winds of 39 mph or higher), of which 7 to 11 could become hurricanes (winds of 74 mph or higher), including 3 to 6 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher).

These ranges are well above the seasonal average of 12 named storms, 6 hurricanes and 3 major hurricanes.

NOAA’s seasonal hurricane outlook is not a hurricane landfall forecast; it does not predict how many storms will hit land or where a storm will strike. Forecasts for individual storms and their impacts will be provided throughout the season by NOAA’s National Hurricane Center.

“This year, oceanic and atmospheric conditions in the Atlantic basin are expected to produce more and stronger hurricanes,” said Gerry Bell, Ph.D., lead hurricane forecaster with NOAA’s Climate Prediction Center. “These conditions include weaker wind shear, warmer Atlantic waters and conducive winds patterns coming from Africa.”

NOAA’s outlook for the Eastern Pacific basin is for a below-normal hurricane season and the Central Pacific basin is also expected to have a below-normal season.

NOAA said it will issue an updated seasonal outlook for the Atlantic hurricane season in early August, just prior to the historical peak of the season.

In July, NOAA plans to bring online a new supercomputer that will run an upgraded Hurricane Weather Research and Forecasting model that provides enhanced depiction of storm structure and improved storm intensity forecast guidance. Also, Doppler radar data will be transmitted in real time.

The National Weather Service has also made changes to allow for hurricane warnings to remain in effect, or to be newly issued, for storms like Sandy that have become post-tropical.
