HOUSTON — A lot of people across Houston are smelling smoke this morning. There's also a smoky haze across parts of the city.
It's coming from a big hardware store fire in north Houston but the smoke spread all the way to the Katy area on the west side.
About 100 Houston Fire Department firefighters battled the flames for hours at the businesses on Jensen Drive just north of 610 near the Eastex Freeway/59.
At last check, they were still monitoring it for hot spots.
No injuries have been reported.
The owner of Martin's said his business has been there for 35 years.
Arson investigators are looking into the cause of the fire.
Surveillance footage is being reviewed to figure out if the fire was set intentionally after witnesses told the owner they saw someone throw something through a window.
"We did have two people come up to us and tell us that they saw a truck throw something through a window," co-owner Carolyn Franco said.
The fire sent thick black smoke billowing into the sky and the smoke spread across the city. KHOU 11 Meteorologist Tim Pandajis said the smoke was locked in near the ground due to a temperature inversion this morning.
Now that we are warming up the inversion will break and surface, mid-level winds will disperse the smoke westwards.
