Hurricane Shary was a short-lived

convection over the Central Atlantic and became a tropical storm on October 28. Initially not expected to exceed wind speeds of 50 mph (85 km/h), Shary defied predictions and became a minimal hurricane on October 30, passing well east of Bermuda. Unfavorable conditions subsequently impacted the storm, and Shary quickly began to lose tropical characteristics. Later that day, Shary degenerated into a post-tropical cyclone, and the final advisory by the National Hurricane Center
was issued.

The storm brushed Bermuda with light rain, and wind gusts reached no more than 35 mph (55 km/h) as it made its closest point of approach to the territory.

In late October 2010, the National Hurricane Center (NHC) began to monitor a weak area of disorganized weather along the southern periphery of a frontal system, associated with a broad surface trough east-northeast of Puerto Rico.[1] Supported by an upper-level low retrograding to its southwest, the system generated clusters of scattered showers and isolated thunderstorms, otherwise known as convection.[2] The activity gradually enhanced as environmental conditions within its encounter became more favorable over time.[3] Around 1200 UTC October 28, satellite imagery showed what appeared to be the formation of a surface low within the trough. Shower and thunderstorm activity accordingly intensified, and the NHC assessed a high chance for tropical or subtropical development.[4] At the time, the center of circulation remained poor; however, it became better defined later that day, with a stable amount of corresponding convection.[5] Although the upper low had remained adjacent, it was located well to the southwest of the system's small wind radius, an atypical structure for a subtropical cyclone.[6] The system was therefore operationally designated as Tropical Storm Shary at 0000 UTC October 29, though post-season analysis revealed a tropical depression had formed by 1800 UTC October 28, about 520 mi (830 km) south-southeast of Bermuda.[7][1] At the time of classification, the agency noted that Shary would be a relatively short-lived tropical cyclone due to a merge with a cold front forecast to occur within the following 48 hours.[6]

Hurricane Hunters flight revealed a drop in minimum central pressure and an increase in maximum wind speeds; convection re-fired later that day, quickly expanding over the eastern side of the cyclone.[10] During the overnight hours, thunderstorm activity further amplified and deepened symmetrically near the center, supported by the development of a small eye feature as noted on microwave images. Although Dvorak classifications were far from supporting such an intensity, the system was upgraded to a Category 1 hurricane with winds of 75 mph (120 km/h) on October 30 — an occurrence which specialists described as a case of a small hurricane that would not have been observed before the availability of microwave satellite imagery. Upon reaching this intensity, Shary was entrenched in a deep, southwesterly mid-latitude flow, resulting in an accelerated motion toward the northeast.[11]

Located just east of a strong

Cape Race, and the NHC discontinued advisories.[13] Later on that day, the extratropical remnants of Hurricane Shary were completely absorbed by the same neighboring system.[1]

Preparations and impact

Immediately following the first advisory on Shary on October 28, the

Hamilton Parish and St. George's Island was temporarily suspended.[15] Local officials urged residents to secure their boats as a safety precaution.[16] The tropical storm warning was canceled during the evening of October 29, as Shary no longer posed a threat to Bermuda.[17]

Since Shary turned away from Bermuda before directly striking the island, its effects were limited. Only 0.54 in (14 mm) of rain fell during the storm's passage, and winds gusted to 35 mph (55 km/h).[18]
