Tropical Storm Rina, the seventeenth named storm of the 2017 Atlantic hurricane season, is gradually gaining strength over the central subtropical Atlantic. As of 10:00 p.m. EST Tuesday, Rina was centered near 35.4°N 48.5°W, and was moving northward at about 18 mph. Maximum sustained winds were 45 knots (50 mph), with an estimated minimum pressure of 1000 mb. Rina is likely to strengthen a little more on Wednesday, partially aided by baroclinic forcing and marginally favorable conditions. Rina should then transition into an extratropical cyclone by early Thursday morning, eventually dissipating without impacting any land areas.
