National Weather Service buying Ammo?

According to this article, the National Weather Service has put out bid solicitations for handgun ammo.  Really.

Why would the National Weather Service need to purchase large quantities of powerful ammo? That’s the question many are asking after the federal agency followed in the footsteps of the Department of Homeland Security in putting out a solicitation for 46,000 rounds of hollow point bullets.

I didn't know that the National Weather Service had an armed contingent. This is getting curiouser and curiouser.
