The use and sale of two types of fireworks—missiles with fins and skyrockets with sticks—will not be allowed in Harris County from Dec. 20–Jan. 1, per a vote Dec. 4 by commissioners court.

When the drought index reaches a certain threshold, commissioners court can enact different preventions, ranging from a burn ban to a ban on fireworks.

"The drought index is about 400 points higher than it normally is this time of year, and we reached that threshold two days ago," said Mike Montgomery, county fire marshal. "This is a precautionary measure."

If the drought index drops below 575 on a scale of 0–800 with 800 being the worst, the ban is automatically rescinded.
