(CNN) The tropical storm Florence, on track to likely hit the East Coast of the US this week, was upgraded to a hurricane Sunday morning. And in a busy start to the 2018 Atlantic hurricane season, two other big storms are brewing right behind it. The National Hurricane Center reclassified Florence as a hurricane in its 11 am report while also issuing advisories in the Atlantic for two other tropical storms expected to become hurricanes: Isaac and Helene. All three named storms (#Florence, #Isaac, and #Helene) likely to become hurricanes in the next 24 - 48 hours. The hurricane center said, "All indications are that Florence will be an extremely dangerous Category 4 hurricane while it moves over the western Atlantic toward the southeastern United States."
