What mic were they using? Typically an omnidirectional microphone is less susceptible to wind, and protection in the form of mesh, foam, calm airspace, etc. also shield the mic capsule from the wind. Also holding the mic close to the mouth increases the signal-to-noise ratio. I have seen many of those storm reporters using Electrovoice RE-50 which is an EV 635 dynamic omnidirectional mic inside lots of vibration and wind protection.
Here are pictures of Electrovoice RE-50 and 635A. They are not quite to the same scale as the 635A fits easily inside the RE-50 case.
