NCCI: Temperature, Precipitation Linked to Frequency

Frequency increases modestly but consistently as temperatures climb, according to a study by the National Council on Compensation Insurance. NCCI said that starting around 50 degrees, there is about a 1% increase in injuries for every five-degree increase in temperature. There are also more injuries on days when the high temperature is around freezing and frequency is lowest on days between 40-60 degrees and days when the temperature is well below 0. At the same time, NCCI said precipitation leads to high claim frequency on freezing days but lessens the frequency increase on warm or hot day...
