Early estimates from Wall Street economists suggest the twin hurricanes that slammed the United States will have a sizable negative impact on third-quarter growth numbers.

Economists shaved their GDP estimates, with Oxford Economics paring 0.4 percentage points on the low end of the range to Goldman Sachs trimming 0.8 points on the high end. Most see the biggest hit from Harvey, with only modest reductions of 0.1 or 0.2 points from Irma.
