GREAT SAND DUNES NATIONAL PARK, Colo. -- A thunderstorm triggered a grass fire Wednesday afternoon at Colorado's Great Sand Dunes National Park, according to park officials.
Lightning sparked the blaze along an entrance road near Highway 150 around 3 p.m., prompting the closure of all inbound traffic to the park, as well as the visitors center.
So far, no evacuations have been needed, and park staff are working with neighboring fire agencies to douse the flames.
The area has been plagued with high fire danger for weeks as gusty winds and low humidity retain its grip.
Fire Weather Warnings remain in effect for southern Colorado into Thursday night for winds up to 60 mph and relative humidity as low as 9%.
The fire weather outlook shows continued critical risk across northern Arizona and New Mexico, southern Utah and Colorado and even the Las Vegas area.
