The shutdown also interfered with the response to the 2018 Sunda Strait tsunami, as the U.S. Embassy in Jakarta's Twitter account was unable to tweet updates, and the United States Geological Survey was unable to provide data on the tsunami. The American weather model, the GFS, suffered a significant drop in forecast quality when a data format change during the shutdown prevented certain weather data from being recognized by the GFS, and the shutdown prevented the bug from being corrected.
