Typhoon Louise Disrupts WWII Invasion of Japan

If Operation Downfall, slated for October 1945, went through, how much disruption would Typhoon Louise have caused to the invasion force?

If the invasion has already begun, how much disruption would this cause the flow of supplies and reinforcements to the landings?

Also, how much heart would this have given Japan's defenders? Given the previous typhoons that disrupted the Mongol invasion, would they think the gods had intervened on their side at last?

This is for a project I've discussed involving Japan being so depopulated by an ATL Allied invasion that the U.S. ends up annexing it, only to face an attempt by nationalist-infiltrated National Guard units to pull a Teutobergerwald on regular American troops and regain independence sometime in the 1970s.

My current idea is that the Kyushu beachhead is established but the typhoon disrupts the flow of reinforcements and supplies. The "third kamikaze" gives the Japanese defenders heart and they attack the beachhead, requiring massive atomic fire support to save it.
 
Would typhoon Louise occur without the nukes falling on Hiroshima and Nagasaki?

Why wouldn't it?

The A-Bombs were fairly small by modern standards. You'd need multi-megaton things akin to the Tambora or Krakatoa eruptions to really disrupt the climate.

But isn't this where the term 'butterfly-effect' comes from? The climate didn't change because of Fat Man and Little Boy but are you sure that the weather isn't changed because of them?

I don't think the "butterfly flaps its wings in Peking and causes a hurricane in America" thing was meant to be taken literally.

I simply don't think that Fat Man and Little Boy are capable of butterflying away a typhoon, especially given their distance from where the typhoon originated.
