Hurricane Irma followed by Jose and Katia in rare Atlantic trio

Irma. Jose. Katia.

Three hurricanes raging at the same time hasn't happened in the Atlantic Ocean since 2010, and at least two of them could affect the Harrisburg area as early as Tuesday, according to the National Weather Service at State College. 

The Category 5 Irma has already left a swath of destruction through the Caribbean and projections show it heading towards Florida, George and the Carolinas, where states of emergencies have already been declared, according to The Weather Channel.

National Hurricane Center projections show Irma reaching southern Florida as a Category 4 storm by 2 a.m. Sunday, then taking a path up the state, hitting Orlando by 2 a.m. Monday and reaching Savannah, Georgia, by 2 a.m. Tuesday, when it drops to Category 1.

However, parts of south Florida and the Keys are already under an official watch as the first of the tropical storm winds from Irma are expected to kick up on Saturday, CNN is reporting.

The other two hurricanes, Jose and Katia, are both Category 1 at the moment. And they are very different storms.

Hurricane Jose is similar to Irma in that it's a Cape Verde hurricane, forming in the far eastern Atlantic, CNN is reporting.

While Jose has the potential to become a major hurricane, it's not expected to take as destructive a path as Irma. Current projections show it moving up the Atlantic, north of the Caribbean islands, becoming a Category 3 or more storm. The Leeward Islands, already devastated by Irma, will be the closest land Jose will encounter, but it should not pass close enough to cause significant destruction, according to reports.

And Katia formed in the Gulf of Mexico off of the coast of Mexico, near where Hurricane Harvey had formed. While Harvey moved north, bringing its destruction to Texas, projections are that Katia sticking close to Mexico, making landfall on Friday, according to the National Hurricane Center.  There is a watch in effect for a small portion of the Mexican coast northeast of Veracruz.

Pennsylvanians do not need to worry about seeing the effects from Katia, National Weather Service meteorologist Paul Head said. But Irma and Jose are another case. 

"We've got some effects that are probably going to take place on Tuesday," Head said, referencing the current weather models for Irma. "We'll see the effects in the form of showers. How much wind remains to be seen."

Current models show the weakening Irma stalling out over Tennessee and Kentucky by Tuesday when the furthest arm of the storm brings rains and the potential for some gusty winds to south-central Pennsylvania. 

As the storm dissipates over the mountains and heads our way, it's on track to bring several drizzly days through about Thursday or Friday of next week.

There is no concern about flooding at this point, Head said. 

And though Jose is currently shown heading north in the Atlantic, several of the 30 weather models offer the possibility that it could move toward the East Coast after Irma dies out, which could bring more rain and wind to Harrisburg. 

"We don't want to dismiss that one just yet," Head said.
