Cloudy and cool, but more regular rain waits until Friday | Weather

The downpours and floods of the 2010s were certainly not limited to the 10 points on this map.

We have more on the notorious storms of the decade here.

But on the rainiest days, these places were wetter than the others.

Superlative one-day rain reports from every year for the past decade have clustered in Tidewater. In half of the cases, the humidity came from a tropical system or its remnants.

And it shows that even in the driest years, when hurricanes move away, an unlucky town can still be inundated by a stranded storm.

The air typically contains the most moisture during the summer, but abnormal patterns also bring big totals in the spring and fall. Recent research also links increased extreme rainfall to the warming of our atmosphere.
