Another hit by two Cat 4+ hurricanes in the same year?
Prior to 2017, the United States had never recorded landfall of more than one hurricane Category 4 or stronger in a single year. Since 1856, only 18 Category 4 and five Category 5 storms have made landfall in the United States. But in 2017 both Hurricanes Harvey and Irma struck as Category 4 storms, hitting Texas and Florida, respectively. Subsequently, hurricane Jose developed into a Category 4 and hurricane Maria strengthened into a Category 5 storm, devastating Puerto Rico.
The highly destructive Atlantic hurricane season has focused attention on the relationship between climate change and the strength of hurricanes. Because warm ocean water fuels hurricanes and warmer water = stronger hurricanes (and climate change = warmer water) stronger storms may become the norm in future decades.
Will two Category 4+ hurricanes hit the United States within the same year in the next five years?
This question will resolve as positive if at least two named Atlantic hurricanes, both classified as Category 4 or 5 storms upon landfall, arrive on the territory of the United States before December 31, 2022. This resolution criteria includes landfall on the Florida Keys or other islands that are part of one of the 50 United States.
Metaculus help: Predicting
Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.
The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.
The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
