Weather forecasters working for the federal government say more tropical activity is likely in the Atlantic Basin, as the second half of Hurricane Season begins. Historically, storm activity increases starting in August.

FOX's Eben Brown reports from Miami:

The updated hurricane season outlook, the official long-term tropical weather forecast from NOAA, now says it is likely this year will produce as many as 12 named tropical storm, with between five and eight becoming hurricanes and of which two to four could become major hurricanes, with wind speed faster a 100 and 10 miles an hour.

NOAA's scientist say signs point to increased activity, and this updated prediction increased the expected number of storms. So far, this year, five Atlantic tropical storms have formed, two which struck the U.S. coast.

Another two grew to hurricane status.
