Wind gust 233 mph after power outage

My power went off then back on suddenly during a storm, when WD restarted it shows an way off wind gust speed of 233 mph . “WD version 10.37s151”. What caused it to do this? And how can I prevent this from happening? Please help Thanks
ps all my weather sites I send data to are showing this erroneous gust speed too.
