Tropical Storm Rina (2017)

Storm Active: November 6-9

On November 3, a weak area of low pressure developed in the central tropical Atlantic, well away from any land areas. It moved slowly north and north-northeast over the following days and became better organized on November 5. Early in the morning on the 6th, the disturbance was organized enough to be classified as Tropical Depression Nineteen. The system was moving over marginal sea surface temperatures in an area of shear that was not too high, so modest strengthening occurred over the next day and the depression became Tropical Storm Rina overnight.

Rina began to accelerate northward on the 7th, passing the latitude of Bermuda almost 1000 miles to the east. Though sea surface temperatures were declining, the system's maximum winds increased some as it took on some subtropical characteristics. Rina reached its peak intensity of 60 mph winds and a pressure of 997 mb on November 8. Later that day it turned toward the north-northeast and began weakening as it transitioned to an extratropical system; it completed this transition during the morning of November 9. The system then turned eastward, eventually impacting the UK as a weak low before dissipation.
