Just in time for Halloween, a spooky set of thunderstorms passed over the Eastern Pacific Ocean today (Oct. 31).
NASA's Terra satellite spotted the ominous brew around midnight Eastern Time. A storm cluster that resembled a jack-o'-lantern with a stem can be seen in the false-color weather image, which highlights the towering clouds.
The weather system is part of Tropical Storm Vance, which is about 450 miles (720 kilometers) south of Acapulco, Mexico. The rare November tropical storm is expected to strengthen into a hurricane by Sunday, NASA said in a statement. Vance is the 20th named storm and would be the 13th hurricane of the season in the Eastern Pacific. Typically, there are no hurricanes in November in the Eastern Pacific, according to statistics from the National Hurricane Center.
