Shary (2010)

A broad low pressure area along a stalled front in the central Atlantic developed organized thunderstorms and became Tropical Depression Shary at 1800 UTC on 28 October 2010 about 450 nautical miles south-southeast of Bermuda. The system strengthened into Tropical Storm Shary at 0000 UTC 29 October and moved generally west-northwest then turned north and northeast as steering currents weakened ahead of a cold front. Shary was short-lived, becoming extratropical by 1800 UTC 30 October and its circulation was absorbed by the front later that day.

Shary did not make landfall. Watches and warnings were issued for Bermuda (a Tropical Storm Watch on 29 October, upgraded to a Tropical Storm Warning later that day), but no tropical-storm-force winds were observed on the island and the storm passed well to the east and north of land.

The cyclone reached peak intensity as a Category 1 hurricane with maximum 1-minute sustained winds of 65 knots (75 mph) and a minimum central pressure of 989 mb. Shary was analyzed to have become a hurricane at 0000 UTC 30 October when an eye feature appeared in microwave satellite imagery; it remained near peak intensity for only a short period before weakening.

There were no reports of storm surge or notable rainfall impacts associated with Shary. No ship reports of tropical-storm-force winds were received, and the only direct marine wind observation used in classification was from NOAA buoy 41049, which measured a 1-minute wind of 33 kt during the tropical storm stage.

No casualties or damage were reported. The storm affected only offshore waters and caused no known impacts on populated areas.

Noteworthy aspects include the rapid organization from a subtropical-like disturbance to a tropical cyclone and the brief appearance of an eye on microwave imagery. Forecasts for Shary had unusually large track and intensity errors compared with recent averages, indicating its motion and intensity were difficult to predict.
