Spring is fire season in Pennsylvania. 85% of our wildfires occur in March, April and May.
There’s no drought in Pennsylvania right now, nor in most of the U.S. — as shown on the map below.
But you don’t need drought to have a fire. All you need are dry conditions, fuel, and a spark. In Pennsylvania we have all three in the spring: low humidity, gusty winds, and lots of old leaf litter drying out in the sun. The spark comes from people.
98% of Pennsylvania’s wildfires are caused by people and most of those are caused by people burning debris. On a sunny windy day those fires blow onto dry grass and escape to the wild. In April 2016 more than 10,000 acres burned in Pennsylvania.
Yesterday the fire danger was high in our state because the weather was so nice — warm and sunny with gusty winds. Across Pennsylvania people were out doing yard work. Some were probably burning piles of debris. I haven’t heard if there were any fires. (The fire danger is lower today, 4 April 2019, because the weather changed.)
If you live in a place that allows outdoor trash burning be careful out there! Spring is Pennsylvania fire season.
