Random Weather Facts

Weather History for June 27
 
1957
Hurricane Audrey smashed ashore at Cameron, LA, drowning 390 persons in the storm tide, and causing 150 million dollars damage in Texas, Louisiana and Mississippi. Audrey left only a brick courthouse and a cement-block icehouse standing at Cameron, and when the waters settled in the town of Crede, only four buildings remained. The powerful winds of Audrey tossed a fishing boat weighing 78 tons onto an off-shore drilling platform. Winds along the coast gusted to 105 mph, and oil rigs off the Louisiana coast reported wind gusts to 180 mph. A storm surge greater than twelve feet inundated the Louisiana coast as much as 25 miles inland. It was the deadliest June hurricane of record for the U.S. (David Ludlum) (The Weather Channel)

1988
The afternoon high of 107 degrees at Bismarck, ND, was a record for the month of June, and Pensacola, FL, equalled their June record with a reading of 101 degrees. Temperatures in the Great Lakes Region and the Ohio Valley dipped into the 40s. (The National Weather Summary)
