Hurricane Season 2013 Highest Risk for USA
The 2013 Atlantic hurricane season starts today , and scientists are warning that it is likely to be a doozy, with more storms than average and more major hurricanes (Category 3 intensity or stronger). Not only are forecasters calling for an unusually active season, they also say that there are signs that the U.S., which hasn’t had a major hurricane in a record seven years, may be particularly vulnerable this year due to a combination of weather and climate factors.
Scientists contacted by Climate Central warned that in part because of the dearth of major hurricanes, there may be a sense of “hurricane amnesia” setting in among coastal residents — a potentially hazardous combination for when the nation’s luck runs out.

NOAA predicts active 2013 Atlantic hurricane season
In its 2013 Atlantic hurricane season outlook issued , NOAA’s Climate Prediction Center is forecasting an active or extremely active season this year. For the six-month hurricane season, which begins June 1, NOAA’s Atlantic Hurricane Season Outlook says 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. “With the devastation of Sandy fresh in our minds, and another active season predicted, everyone at NOAA is committed to providing life-saving forecasts in the face of these storms and ensuring that Americans are prepared and ready ahead of time.” said Kathryn Sullivan PhD, NOAA acting administrator. “As we saw first-hand with Sandy, it’s important to remember that tropical storm and hurricane impacts are not limited to the coastline. Strong winds, torrential rain, flooding, and tornadoes often threaten inland areas far from where the storm first makes landfall.” Three climate factors that strongly control Atlantic hurricane activity are expected to come together to produce an active or extremely active 2013 hurricane season. These are:
- A continuation of the atmospheric climate pattern, which includes a strong west African monsoon, that is responsible for the ongoing era of high activity for Atlantic hurricanes that began in 1995;
- Warmer-than-average water temperatures in the tropical Atlantic Ocean and Caribbean Sea; and
- El Niño is not expected to develop and suppress hurricane formation.
“This year, oceanic and atmospheric conditions in the Atlantic basin are expected to produce more and stronger hurricanes,” said Gerry Bell, Ph.D., lead seasonal 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 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.
