It is also of note that a Flash Flood Watch is in effect from very early Sunday morning through Monday afternoon for most of the state (only the far SW and the extreme northern tiers of counties are not in the watch). Another 1-2 inches or more of rain is expected between now and Monday afternoon, this could not only lead to the flash flooding threat, but also more rises in area rivers and streams as indicated earlier in this post.
