The National Weather Service files these reports in its Local Storm Reports. A storm collects any two reports that fell no more than 75 miles and 6 hours apart, and any report already linked to either one joins that storm too, even when the reports sit in different states. Storms that last more than 48 hours are divided at the hour where reports are fewest, and each part is checked again. A page needs 5 reports or a top of 2 inches, and at least 3 reports either way.
