Hurricane Delta's winds were strong, and we had several official reports from the National Weather Service. Sometimes these "official" wind speeds don't match up with what people observe, or damage associated with those speeds don't seem high enough. Sometimes, the official weather reporting stations could have had equipment failure, mainly due to the loss of power.
With today's technology, many have backyard weather stations. It's great information, and usually is true to the actual weather conditions between the "official" reporting stations. In this case, the reporting station was at Pecan Island. The image was sent to us from Brennan Billeaud who says the speed was measured at his parent's camp. This reading would be right about what wind speeds were with Hurricane Delta right as the system reached land. Delta came onshore as a strong Category 2 hurricane.
