Cape Cod, Massachusetts, ARES, and SKYWARN Amateur Radio volunteers were promptly pressed into action as a storm system on July 23 produced severe thunderstorms that spawned three tornadoes over the Cape. Hurricane-force wind also resulted in significant tree and utility wire damage across Cape Cod, with particularly hard-hit communities including Hyannis, Yarmouth, and Chatham. Some pockets of wind damage also occurred in the northwest corner of Martha’s Vineyard.
Amateur Radio SKYWARN spotters were the first to provide critical ground truth information regarding the significant wind damage and tornadoes across Cape Cod. Under the direction of Cape Cod District Emergency Coordinator Frank O’Laughlin, WQ1O, and Eastern Massachusetts Section Emergency Coordinator Rob Macedo, KD1CY, a SKYWARN net ran for several hour on a Barnstable, Massachusetts, VHF repeater. Numerous damage reports were received during the net and for a couple hours after the storm had passed.
At that point, Amateur Radio operations shifted to an ARES net supporting communications between a shelter at the Dennis-Yarmouth School and the Barnstable County Emergency Operations Center, which serves as the Multiagency Coordination Center (MACC).
