During the Atlantic hurricane season, it’s important for us all to know the tropical weather terms that may be used by meteorologists over the next several months. Did you know that understanding tropical terminology can help you stay informed and prepared this hurricane season?
From tropical disturbances to hurricanes, we’re highlighting the most common terms used to describe areas of tropical weather. Officials may use these terms if they need to issue important weather alerts.
Test your weather knowledge and get to know these terms:
