Today, the self-styled "civilian intelligence analyst" and "specialist in photo interpretation, geometric analysis and computer imaging" (who can't tell the difference between a 166-mile wide space station and a 2ft sheet of mylar insulation) posted this prediction:
"Mars' passage close to Earth on July 31st, 2018 will created [sic] super storms like Katrina (again, as it did i 2003), along with volcanic activity and intense electrical storms around the globe. Be ready for something and anything."We'll be watching.
Update 20th July:
Severe tornadoes ripped through Iowa, partly destroying Marshalltown. Nothing to do with Mars.
A different storm sank a boat in a Missouri lake, drowning 17. Nothing to do with Mars, either.
6.0 magnitude earthquake, Papua New Guinea. Nothing to do with Mars.
Update 21st July:
Scorching (110°F) weather in Texas, persistent drought in the UK. Nothing to do with Mars.
Update 22nd July:
5.9 magnitude earthquake, Kermanshah, Iran. Nothing to do with Mars.
Floods/landslides in Vietnam kill 21. Nothing to do with Mars.
Update 23rd July:
Record-breaking heatwave in Japan, dozens dead. Nothing to do with Mars.
5.9 magnitude earthquake, mid-atlantic ridge. Nothing to do with Mars.
Reports that Germany is running out of beer bottles because of a heatwave. Mars?
Update 24th July:
60 dead in Greek wildfires. Nothing to do with Mars.
Dam collapses in Laos. Hundreds missing. Nothing to do with Mars.
Update 25th July:
Exceptionally heavy rain on the East US coast brings flooding. Nothing to do with Mars.
Update 27th July:
Ambae island in Vanuatu evacuated as the Manaro Voui volcano began spewing ash. Nothing to do with Mars.
Update 28th July:
Severe storm (but not "super-storm") continues on US East coast. 500 buildings destroyed by fire in Redding, CA. Notable (although perhaps not "intense") electrical storm over the North Sea, extending into Germany. Nothing to do with Mars.
Update 29th July:
6.4 magnitude earthquake, Lombok, Inodnesia. 14 dead. Typhoon Jongdarinote 1 caused chaos in Japan. Mars is coming!!! (allegedly)
Robert Morningstar has now written that the effect of close approach will last for "at least three weeks." Clever — he hopes thereby to give himself a lot more time to claim that his predictions were accurate, and to guarantee that everyone will have forgotten his exact prediction by the time his window closes. I'm not buying it.
30th July ======== ZONE OF CLAIMED MARS INFLUENCE ==========
Typhoon Jongdari downgraded to "tropical storm."
California brush fires continued (having begun a week ago). The volcanic sequence in Hawaii continued (having begun 30 April). Some Indonesian volcanoes continued to belch (as they have been doing for a few thousand years).
A fairly impressive belt of lightning persisted over Europe, but electrical activity over the Americas was normal, and that over Oceania and Australasia abnormally quiet.
Lightning map, Oceania/Australasia 30 July 2018. Pretty peaceful.
Nothing to report today.
Morningstar reminds me that there's a tropical cyclone over Mexico, but, y'know, it's the season for that. There's nothing remotely unusual about this one.
Nothing going on today. No major eruptions or earthquakes worldwide. Even the European lightning map shows much less activity. The Mexican tropical storm developed into a named event, "Hector," but it's a very junior hurricane with winds 35 knots gusting to 45.
======== END ZONE OF CLAIMED MARS INFLUENCE ==========
Now please see Robert Morningstar: FAIL!!! for an assessment.
 July and August are peak months for typhoons (a.k.a. Pacific tropical cyclones). Over the period 1959-2015, those months saw average numbers of 3.9 and 5.4 respectively. In other words, it would be highly surprising if there were not any typhoons during this period (ref: Wikipedia).
