Forecasters expect a near-normal Atlantic hurricane season, after three relatively slow years. They also say climate conditions that influence storm development are making it difficult to predict how many hurricanes and tropical storms will arise over the next six months.

NOAA's season outlook calls for 10 to 16 named storms, with four to eight hurricanes and one to four "major" ones with winds reaching 111 mph and up.

The Atlantic hurricane season officially starts June 1.
