Tropical Rain in North Dakota?!

29 Nov 2017, 4:45 pm

With the end of the Atlantic hurricane season upon us, things are typically quieter in the tropics this time of year.  That’s not always the case, however.  The Atlantic hurricane season—officially June 1 through November 30—is just a general time frame for tracking tropical systems.  In fact, tropical storms have formed as early as January (Hurricane Alex, 2016) and as late as December (Tropical Storm Zeta, 2005).

If the conditions are right, tropical systems can form at any time of year.  With that in mind it should come as no surprise that hurricanes, tropical storms, and their remnants can also impact a wide variety of places.  Just this year, Hurricane Ophelia’s remnants hit Ireland and Norway.  In the United States, the major impacts of wind and storm surge are typically found in or near coastal states.  But tropical rain has fallen over all 50 states.  The southern section of the country leads the list with heaviest maximum rainfall totals per state.  Texas tops the list with 60.58″ of rain from Hurricane Harvey in 2017.

Of the Mid-Atlantic states, Virginia leads the pack with 27.00″ of rain from Hurricane Camille in 1969.

Further north in New England, Hurricane Diane in 1955 dropped 19.75″ of rain in Massachusetts.

What might be even more interesting is the fact that states such as Missouri, Kansas, and even Arizona have picked up nearly one foot of rain from a tropical system!  Check out this map, courtesy of the National Oceanic and Atmospheric Administration.

Yes, even a state far removed from an ocean such as North Dakota has had tropical rainfall.  Pretty cool, right?!
