An early appearance for the Atlantic’s first named storm of 2017?
The models are predicting the formation of a large area of low pressure a few hundred miles east of the Bahamas on Sunday and Monday, and this low has the potential to acquire characteristics of a subtropical storm as it heads north and then northeast, passing a few hundred miles southeast of Bermuda on Tuesday. Water temperatures in the region are near 24°C (75°F), which is near average, and these waters may be barely warm enough to support formation of a subtropical depression or subtropical storm. According to phase space diagrams from Florida State University, the low will initially have a warm core that will gradually weaken as the storm encounters cooler waters near 21°C (70°F) by Tuesday. We give 5-day odds of 10% of this low becoming a subtropical depression or subtropical storm. According to NOAA’s Historical Hurricane Tracks, the only March tropical cyclone ever recorded in the Atlantic was a Category 2 hurricane that passed through the Lesser Antilles on March 8, 1908.

There is no way that I would want to go out there and sail in the deep blue when you have a potential named storm floating around. I'll happily wait in harbor for another day or two.
