A match thrown down in a healthy forest won’t produce a massive apocalyptic firestorm.
No matter the time of year.
Even back in the 70’s the National Park service in Yosemite knew the existing forest management practice was creating apocalyptic fire risk (and the ‘91 Yosemite fire bore that out) but until very recently, practices across the state have been unchanged.
Defacto, walk through the forests in California and the build up of brush is monumental. Along the coasts and in the Sierra Nevada. Many areas are impassible, except those that have burned recently.
