Tropical development possible in Atlantic over Labor Day weekend

With the peak of hurricane season close at hand, there are signs that the tropical Atlantic may soon spring to life with the potential for direct impact on the coastal United States in the days ahead.

The National Weather Service defines a hurricane as "an intense tropical weather system with well-defined circulation and sustained winds of 74 miles per hour (64 knots) or higher".

According to the National weather service, "significant flooding" struck many areas in the North-Eastern and Eastern slopes of the Big island.

Meanwhile, Tropical Storm Miriam churned over the eastern Pacific with maximum winds of 60 miles per hour (95 kph).

Now residents are keeping a watchful eye on Tropical Storm Miriam, which is spinning about 3,000 kilometres to the east and moving west towards Hawaii. There is a weak area of showers and storms near the northeast Caribbean.

Hurricane Lane soaked Hawaii's Big Island on Thursday, dumping almost 20 inches of rain in almost 24 hours as residents stocked up on supplies and tried to protect their homes ahead of the state's first hurricane since 1992. NASA research has shown that storms with cloud top temperatures that cold (that are very high in the troposphere) have the capability to generate heavy rain.
