In updated outlook, NOAA says hurricane season could become ‘extremely active’
Other factors that point to an above-normal season include warmer waters across the tropical Atlantic than models previously predicted and higher predicted activity from available models, according to Bell.
An average season produces 12 named storms of which six become hurricanes, including three major hurricanes. Since the beginning of hurricane season on June 1, there have been six named storms, which is half the number of storms during an average six-month season and double the number of storms that would typically form by early August.
“Today’s updated outlook underscores the need for everyone to know their true vulnerabilities to storms and storm surge,” said FEMA Administrator Brock Long. “As we enter the height of hurricane season, it’s important for everyone to know who issues evacuation orders in their community, heed the warnings, update their insurance and have a preparedness plan.”
Some Atlantic basin seasons feature below average activity but still result in a devastating storm, like Hurricane Andrew in 1992, while others like 2010 — third most active season on record — did not feature a hurricane making landfall.
The 2017 Atlantic basin hurricane season will end on November 30. The upcoming names include Gert, Harvey, Irma, Jose, Katina, Lee, and Maria.
The season peaks in September, and 80 percent of named storms between 1981 and 2010 have formed between August and October.
