Some of our worst fires in California were the summer after winters with extreme rain events.
If you have a dry season, you can have a fire season, and the wetter your wet season, the worse fire season will be.
The Northeast doesn't have a dry season, and I don't think anyone seriously thinks it's going to develop one. It just has occasional dry periods because precipitation is pretty chaotic, and is getting more chaotic due to climate change. When one of those happens there's some fire risk, like has just happened. "The Northeast is becoming fire country" is just unabashed scare mongering.
The northeast woods does not have a wet/dry seasonality the way fire country in the West does.
In the West, the wettest month (which is in winter) can have 6-10 inches of rain while the driest (which is in summer) has 0-0.5 inch.
In the northeast, the wettest month (which is in SUMMER), might be 3-5 inches. The driest (which is in WINTER) might be 2-3 inches, including snowfall.
