7 IX 2019: Who is the real author of NOAA’s announcement?

Today’s news reports the issue of an anonymous statement by the National Oceanographic and Atmospheric Administration that criticizes the National Weather Service’s announcement that Dorian posed absolutely no threat to the Great State of Alabama.

Why was this statement anonymous, i.e., not signed by anyone in the NDAA? I supose they couldn’t find any practiced liars from the Trump Organization in their agency. Maybe they had an intern write it. Why did they take so long issuing this corrective? Should we take it at all seriously?

Maybe the agency did in fact issue the statement, because NOAA did not want to have its budget reallocated to Homeland inSecurity. So they threw Trump a lifebuoy, even if suspiciously late. 

OR, maybe it was not NOAA at all, but a Trumpian operative using NOAA letterhead. To test this hypothesis, I want to know first of all: Was the statement typewritten? or was it written with a Sharpie pen?
