Key Factors Driving NOAA's Forecast - GOHSEP | Governor's Office of Homeland Security & Emergency Preparedness

The Atlantic season is expected to be below-normal due to competing factors. El Niño is expected to develop and intensify during the hurricane season, while ocean temperatures in the Atlantic are expected to be slightly warmer than normal and trade winds are likely weaker than average. El Niño conditions tend to support less tropical storms and hurricanes, while warmer ocean temperatures and low winds support a more active year.

“Although El Niño’s impact in the Atlantic Basin can often suppress hurricane development, there is still uncertainty in how each season will unfold,” said NOAA’s National Weather Service Director Ken Graham. “That is why it’s essential to review your hurricane preparedness plan now. It only takes one storm to make for a very bad season.”

NOAA’s outlook is for overall seasonal activity based on large-scale weather and climate patterns. It does not indicate where or when any storms may affect land as that is determined by short-term and variable weather patterns. The outlook is not a landfall forecast.

“Preparing now for hurricane season — and not waiting for a storm to threaten — is essential for staying ahead of any storm. Visit http://weather.gov/safety and Ready.gov (http://ready.gov/) for important preparedness information,” added Graham.
