The National Hurricane Center cautioned that Hurricane Henri could bring the following threats:
- Henri is expected to bring three to six inches of rain on Long Island, New England, southeastern New York, and Northern New Jersey on Sunday into Monday, with isolated totals of up to 10 inches, the center said.
- Heavy rainfall could produce flooding in some areas.
- Along with a storm surge of up to five feet, the center said the storm could also be “accompanied by large and dangerous waves.”
- Once it makes landfall, the center said Henri could produce a couple of tornadoes over southern New England.
- Henri could also bring dangerous swells to much of the east coast. “These swells could cause life-threatening surf and rip current conditions,” the center said.
