Tropical Storm Chantel was formed in the North Atlantic on Aug. 21 and has weakened to a tropical depression.
“The cyclone should continue to move through a dry mid- to low-level air mass, with humidities less than 40 percent, during the next few days. This is likely to cause weakening, and it is expected that Chantal will become a tropical depression tomorrow and a remnant low by Friday,” the National Weather Service’s National Hurricane Center said in an Aug. 21 statement.
