Questions answered by the reporting
Which Colorado areas face the greatest reported flood threat?
The strongest activity is expected east of Denver and south of the Palmer Divide, including the San Luis Valley; the San Juan Mountains also have a high flood threat. [1]
Why can rain worsen flooding despite drought conditions?
Very dry ground may not absorb prolonged rainfall quickly, allowing runoff and flooding even while the rain provides some drought relief. [1]
