There’s a better link but the website seems to be down. This link shows a map of direct strikes from hurricanes, split into smaller groups than “northeast”, “southeast”, et. Al. http://www.csc.noaa.gov/hurricanes
CDI approves every rate change. Between marginally higher risks, inflation, new costs (e.g. re-capitalising the FAIR Plan for people who like living inside wildfires) and the risk that future rates won't be approved, the cost basis is likely quite a bit higher than 50%, particularly if you take into account prior years covered by the pandemic rate-hike moratorium [1].
