Snow blowing in gable vents

At work I over see a one story office building that is getting snow blowing in the gable vents. There are ten triangle gable vents that are placed in dog house dormers that are aproximitly 4 ft tall and 9 ft wide. When it is windy and it snowing the snow seams to find its way past the insect screen in the vents and causes leaks in the office building, What sugestions do you have to corect this.

My first choice would be to block those vents and add ridge venting. Is that possible?

A temporary fix is to add some sort of wind dampener like tyvek, sheet plastic, landscape fabric or such to stop the wind and the unwelcome snow. The bad part of this is having to remember to take it down in spring, which most people forget about, which is why ridge venting is preferred.

Howdy, the snow is finer then the screen one can ad another layer of finer screen. Or have seen fiberglass filter material d****d across the inside of the vent. It allows the air to flow but the snow coats the filter and stops any additional intrusion. Later the skim coat of snow melts and no interior water damage The snow melts an no water damage and the filters left in place for years and years.

Bad advice, don't do this.
You don't want to seal off the venting even during the winter.

The simplest thing would be to use a batt of fiber glass insulation about an inch or two thick.
This will allow air flow but trap snow from entering.
