They are calling it "Sand-nado" after the popular movie Sharknado, after a crazy dust devil forms in the middle of a Brooklyn park. 

Onlookers freak out as this dust devil forms into a crazy twister right in the middle of a baseball field. It's crazy to hear some people laughing and some panicking while this mini tornado takes shape and starts blowing everything around.

Experts are calling it a very rare Dust Devil that are only formed under certain and perfect conditions, which has happened right in the middle of this baseball field. Usually dust devils are common in deserts only for obvious reasons.
