Region	1986	1989	2003
Northern Atlantic	June, August, September, November	June, July, August, September, October, November, December	April, June, July, August, September, October, November, December
Eastern Pacific	May, June, July, August, September, October	January, May, June, July, August, September, October	January, May, June, July, August, September, October
Western Pacific	Throughout the year	January, April, May, June, July, August, September, October, November, December	April, May, June, July, August, September, October, November, December

We indicate the months when storms were observed in those years. As seen from the table, the storm was observed in the Eastern Pacific in May 1986. It had existed May 22–29 which cannot be associated with the May 3, 1986 magnetic storm. Yet, it corroborates the climatology of tropical cyclone (tropical cyclones originate in the Pacific Ocean, May through November).
