Note: These tropical storms mostly affect the west side of the Atlantic, though some bigger storms sometimes hop over to Europe after losing most of their energy.
Although the Atlantic hurricane season begins June 1, the bulk of the tropical activity typically clusters during the middle months of August, September, and October when the seas reach their peak temperatures. This year has already been unusual, however, with the formation of highly rare tropical storm in April—Arlene, which meandered around the open Atlantic Ocean for a few days.
Now, the tropics are becoming active again. For several days the National Hurricane Center has been calling attention to two systems, one near the southern Gulf of Mexico, and the other to the northeast of Venezuela in the Atlantic. Both systems have a 90 percent chance of becoming a tropical depression or storm, according to hurricane forecasters at the Miami-based center.
