Flooding, 2010-'14

The recent floods in the Midwest got us wondering about the sub-seasonal to seasonal predictability of other flooding events that have occurred in the US during the last few years. For example, last september (Fall of 2013), parts of Colorado experienced record-setting rainfall, which triggered severe flooding throughout the state for the rest of the month.

Is it megadrought?

Hurricane Arthur: an Historical Perspective

Arthur, the first named tropical storm and now hurricane of the season, has stirred up the commotion associated with approaching storms of this caliber. By the afternoon of July 2nd, the tropical storm was 110 miles east-northeast of Cape Canaveral, Florida, and its sustained winds had so far peaked at 60 mph (95 km/hour) while it was traveling north, up the East Coast, at 7 mph (11 km/hour) [1]. By the following afternoon, Arthur intensified, reaching category one status, and its highest sustained winds rose to 90 mph (150 km/hour) as the storm was roughly 225 miles southwest of Cape Hatteras, North Carolina and traveling north-northeast at an increased forward speed of 13 mph (20 km/hour) [2].

Water everywhere?

Although Hurricane Arthur has dominated the news over the last few days, the proceeding few weeks have seen their own fair share of severe weather here and abroad. Flooding began this June throughout the Midwest, and conditions have been especially worse in Minnesota. Governor Mark Dayton declared a state of emergency in 35 of Minnesota’s counties, as crops, roadways, homes, and businesses were damaged on a geographically large scale [1].
