Indirect deaths from hurricanes from 1963-2012 numbered 1,418 but Maria in Puerto Rico alone caused 2,911?

My mother died of old age related heart failure two days after Hurricane Gustav made landfall in Louisiana in 2008:

48 deaths in the state of Louisiana were blamed on Hurricane Gustav. Five were due to falling trees, two due to a tornado and the rest were indirect deaths.

My mother wasn't counted among the 41 indirect deaths in Louisiana, for the main reason that she died in a different state.

But . . .

Hurricane Fatality Reports Leave Out Thousands of Indirect Deaths, According to New Study:

Looking at 59 hurricanes in the Atlantic Basin from 1963 through 2012, the study found that those systems killed a combined 1,803 people directly – by forces like flooding and airborne debris that were caused by the storm itself. But there were also a slew of lingering impacts that proved deadly in those storms, which caused 1,418 "indirect" deaths, according to the findings. ... Nearly half of the indirect deaths attributed to these 59 hurricanes were heart attacks, according to the study's data. Automobile accidents were also a major threat to life, whether the crashes occurred during evacuation or after the storm.

So we're supposed to believe tonight that about 2,911 (2,975-64) Puerto Ricans died indirectly in consequence of one storm (Maria) over the next six months according to the new math of George Washington University and Harvard University when over the course of nearly 50 years' worth of hurricanes indirect deaths for all storms combined came to just 1,418.

Sure we are.
