Tropical Storm Grace holds the record for being the farthest northeast forming tropical cyclone in the Atlantic basin.[1] The seventh named storm of the slightly below average 2009 Atlantic hurricane season, Grace formed from an extratropical cyclone over the Azores on 4 October. It strengthened to attain peak sustained winds of 65 mph (100 km/h) and developed an eye-like feature, although cold sea surface temperatures inhibited the development of thunderstorm activity near the center. The storm lost its tropical characteristics on 6 October, and the storm's remnants merged with a separate system near the British Isles on 7 October.
Grace had only minor effects on land, although while it was passing through the Azores, islands close to the storm's center recorded winds of up to 44 mph (71 km/h) and moderate rainfall. Although not solely related to the cyclone, heavy rainfall in Portugal led to some street flooding. The remnants also impacted parts of Ireland and the United Kingdom, where rainfall approaching 2 in (51 mm) and tropical storm-force winds were recorded. However, no damage occurred.
