Super Typhoon Maria sets record, threatens Japan, China

While the storm is likely to be somewhat weaker by the time it makes landfall, it could still strike as a super typhoon or a strong typhoon that would result in widespread flooding, a deadly coastal storm surge, and damage from high winds. Some meteorologists are already sounding the alarm for mainland China.

Between the lines: Hurricane Maria devastated the island of Puerto Rico last year, and at one point was a Category 5 storm. There will never again be another Hurricane Maria in the Atlantic Ocean, since that name was retired by a storm naming committee that is overseen by the World Meteorological Organization.

Record falls: However, there is a separate storm name list for Pacific typhoons, so now we have another powerful "Maria." This sets a record for the first back-to-back storms with the same name to each reach Category 5 intensity, but in different ocean basins.
