A strengthening tropical storm slowly moving through the Caribbean could turn into a rare late November hurricane by Wednesday, according to the National Hurricane Center.
Tropical Storm Otto formed on Monday and is lurking near the coastlines of Panama, Costa Rica and Nicaragua.
The slowly moving system with maximum sustained winds at 70 mph is expected to gain strength over the next 48 hours as it moves erratically in a west-northwestward motion, the National Hurricane Center said in a statement. It is likely to become a hurricane by Wednesday.

Otto will likely make landfall as a hurricane, according to AccuWeather. It is not a threat to the United States.
A tropical storm warning has been issued for San Andres, Colombia. Otto could bring flooding, mudslides and damaging winds this week to the Central American region, according to AccuWeather.
Dangerously rough seas and coastal flooding are expected in the region over the next few days. Otto is projected to lose strength as it hits the mountains in Central America later this week.
November hurricanes and tropical storms are rare but are more likely to form in the Caribbean, according to the Weather Channel. Since 1851, there have been 58 hurricanes and 89 tropical storms in the Atlantic in the month of November, compared to 395 hurricanes and 571 tropical storms in September, the most common month for tropical weather.
Hurricane Kate in 1985 was the last November hurricane to make landfall in the United States. It was also the last tropical storm to make landfall in November in South Carolina.
The Atlantic hurricane season ends Nov. 30. There have been 15 named storms and six hurricanes so far this year. Hurricane Matthew was by far the deadliest and most destructive storm of the year.
