Rainy November brings end to 2015 hurricane season

A quiet hurricane season ended Monday with 11 named storms for the year, four of which reached hurricane strength. None had major effects on the Cayman Islands.
November, while quiet for tropical storms, saw almost double the average rainfall for the month. More than 11 inches of rain fell in the month, according to the Cayman Islands Weather Service.

Forecasters say they expect clouds and rain coming off a tropical system and moving through the region through Saturday.

“This is typically a transitional month for us,” said Weather Service forecaster Gilbert Miller, looking to the month ahead. He said December traditionally marks the end of the rainy season in Cayman as cold fronts from the north take over from the tropical systems to the south.

Winston Gall, also with the Weather Service, said November’s 11.4 inches of rain is on the high side for the month – the 30-year average for November is 6 inches according to Weather Service data – however it is just half the record for November rainfall, set in 1996 when heavy storms brought more than 22 inches of rain to the Cayman Islands.

“This has been system driven,” he said, with upper-level conditions bringing the extra rain to the islands.

The past month has been much wetter than October, which is typically one of the rainiest months for the Cayman Islands. Almost 5 inches of rain fell in October, well below the 30-year average of more than 8.5 inches.

Mr. Miller said the skies will be mostly cloudy through this week with some showers and thunderstorms. He warned that the storms could be heavy at times and the islands may see some local flooding.

Of the 11 named storms, no hurricanes or tropical depressions hit the Cayman Islands this year, though the territory did see several tropical waves move through, with flooding rains and winds that caused minor damage.
