Here’s all you need to know about Hurricane Henri as it heads towards New York City and New England.

HUH! A HURRICANE IS ATTACKING NEW ENGLAND

Perhaps! Rare tropical weather is making its way up off the Atlantic coast of the U.S., destined for New York and New England — two regions that don’t often play host to tropical systems.

WHAT AREAS IS HENRI SUPPOSED to AFFECT?

It looks like New York’s Long Island, and southern New England — especially Connecticut — will be affected by it. If it makes landfall in New York, that would be the first time the state’s sustained a direct hit during a hurricane season since 2012’s Superstorm Sandy — the effects of which are still plaguing New York. Either way, it’s expected to make landfall Sunday, but effects could be felt as soon as Saturday.

WHO IS HENRI WHO IS BOB WHO IS GLORIA

Stormy trio. Henri became a hurricane on Saturday morning. It could be New England’s first hurricane in 30 years. Bob was its predecessor, responsible for the deaths of 17 and $1.5 billion in damage in August 1991. Henri is focusing on Connecticut, so it’s worth remembering Gloria — the September 1985 hurricane that struck Long Island and Connecticut caused eight deaths and almost $1 billion in damages.

JE M’APPELLE HENRI — WHY SHARE A NAME With A HURRICANE

These storms have human names courtesy the World Meteorological Association, which draws up a list of 21 names for each Atlantic hurricane season.

What are the conditions for a HENRI, BOB or GLORIA?

Two ingredients are required for a storm’s ability to track so far north: a tropical system and steering currents. According to the National Weather Service, most tropical systems in northern hemisphere tend to run out or recur before they make it north.

OK, THIS IS PRETTY RARE. IS HENRI’S WAY CONNECTED WITH CLIMATE CHANGE AND HENRI’S PATH?

No, perhaps surprisingly. According to the National Weather Service, it’s a tropical weather phenomenon. It is not normal to expect more New England tropical storms.

What can people do to prepare for HENRI?

This is not New England’s or New York’s first rodeo featuring weather at its worst. A nor’easter, after all, is just a hurricane with Boston accent. The Long Island dialect is also able to do the same. The usual protocol applies: Take boats out of the water, fill up your cars with gas, stock your pantry, and close the hatches. Prepare for power outages.

WE ARE IN THE DOG DAYS of AUGUST — ARE STILL TOURISTS ON ATLANTIC COAST?

Yes. Yes, indeed. Although school is back in session on some parts of the east coast there are still thousands of tourists who enjoy the beaches of Cape Cod, Hamptons, and other areas.
