AsTropical Storm Dexter moves further out into the Atlantic Oceanand away from any potential risk to land, hurricane forecasters have their eyes ontwo other disturbancesbrewing in early August. Dexter, which formed over the weekend, was weakening on Aug. 5 as it battled shearing winds on its path northeastward away from the U.S. coast, according to theNational Hurricane Center. As of midday, it was positioned about 400 miles north of Bermuda, putting it over 600 miles off the East Coast. There were no coastal watches or warnings for weather impacts from the tropical storm. Forecasters say Dexter should keep going at its current rate of about 12 mph with little change over the next couple days, but could re-intensify as a post-tropical cyclone later in the week. Meanwhile, two more areas of possible concern include a disturbance off the Southeast coast of the United States with a 40% chance of formation over the next week, the hurricane center said. That broad area of low pressure could develop several hundred miles off the coast and might spell rainfall for beachgoers. The other, a tropical wave producing showers over the far eastern tropical Atlantic recently moved off the coast of Africa and has a 50% chance of becoming a cyclone; forecasters said it could become a tropical depression later in the week. Dexter was the fourth named storm of the Atlantic hurricane season, putting it on par with an average hurricane season, which usually has a fourth named storm by Aug. 3, according to Philip Klotzbach, a senior research scientist at Colorado State University. The average date of the first hurricane in the Atlantic is Aug. 15. If the other two disturbances form into named storms,they would be called Erin and Fernand. "We are now moving into a more active period (of the) Atlantic hurricane season,"Weather Trader meteorologist Ryan Mauetold USA TODAY on Aug. 4. The Atlantic hurricane season officially began on June 1 and will last through the end of November. Active hurricane weather typically peaks between mid-August and mid-October. Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees Fahrenheit. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression. A tropical depression becomes a tropical storm once its sustained wind speeds reach 39 miles per hour. When its winds reach 74 mph, the storm officially becomes a hurricane.
