March 2025 Microburst and Mast Repair

On Sunday, March 16, 2025, at 2:30 PM, a line of severe thunderstorms passed through our area. A high wind of 46 mph ripped out the guy lines of my weather mast and bent it over by 45 degrees. The State College NWS Office (CTP) reported microbursts in the area so it is possible that the wind speeds were higher. More information about the storm:

Damaged Mast
High Wind Speed Before Instrument Failure

I removed the damaged 16 gauge 10’ mast section (pictured below).

I installed two new 5′ mast sections and a new wind sensor package. The wind direction sensor had been behaving erroneously several weeks before the storm. The mast was hoisted into place and secured to the fence post with new hose clamps. The wind sensor cable was plugged into the weather station transmitter and secured with cable ties. The guy lines were then staked to the ground.

Repaired weather mast.
