current predictions say 65-85mph winds in your area, with heavy rain and flooding. I would be concerned about a tarp although well anchored holding things down. Is it open in the back yard or near the house? Parking it near a building on the leeward side of the wind will help. Stay safe!
Found this online:
65-85 mph - LIGHT DAMAGE: Some damage to chimneys, TV antennas, roof shingles displaced. Small branches broken on trees.
86-110 mph - MODERATE DAMAGE: Roof decking removed, carports overturned, some trees uprooted, automobiles overturned. Unanchored homes sliding.
