UPDATE: Katharine moved closer to shore Tuesday night, pinging at 6:14 p.m. offshore between Hobe Sound and Port Salerno.

The St. Lucie Marine Protected Area, the area where Katharine last surfaced, is about 9 miles southeast of the St. Lucie Inlet.

Katharine could be chasing bonito, blackfin tuna, wahoo, king mackerel or Spanish mackerel in the area, according to TCPalm's outdoors journalist Ed Killer.

EARLIER STORY

Katharine the Shark's definitely headed for warmer water.

Possibly trying to skirt the cool front that's wandered into the Treasure Coast, the 14-foot, 2,300-pound great white surfaced offshore of Port Salerno, heading toward Jupiter, at 6:43 p.m. Monday.

According to OCEARCH — a great white shark research and advocacy team that tags and tracks sharks, turtles, whales and other sea creatures — Katharine spent most of the winter of 2017 and early 2018 offshore along the East Coast of Florida and the Bahamas.

So far, Katharine's traveled more than 36,000 miles, according to OCEARCH.

This is the fifth time in less than one month that Katharine has surfaced along the Space and Treasure coasts.

On Black Friday, Katharine, surfaced near Melbourne and brought along a friend, DeMott — a tiger shark named after David DeMott, one of the four founders of SeaWorld in 1964. Then, Katharine pinged three times in one day, about 30 miles offshore of Fort Pierce.

Until recently, Katharine had been silent since January. Then, following Hurricane Florence, she pinged Sept. 20 near Kitty Hawk, North Carolina. Then on Nov. 15, she surfaced near Charleston, South Carolina.

Katharine — tagged in August 2013 near Cape Cod, Massachusetts — was named by Cat Products fans in honor of Katharine Lee Bates, a Cape Cod native and songwriter, best known for her poem and song "America The Beautiful," which has been called "an expression of patriotism at its finest."

According to OCEARCH, Katharine's tracker battery is close to running out, so researchers are excited about additional pings. A tracker battery lasts about five years.

Katharine's trips to the Treasure Coast

Katharine spent the first several months of 2017 swimming around between Fort Pierce and Titusville.

After disappearing for a few months, Katharine popped up east of Vero Beach April 19, 2017. She wandered around on a generally northward path, pinging several times off Brevard County in May 2017.

She also spent a lot of time near the Treasure Coast and throughout Florida in 2014.

According to her tracking device, Katharine’s Treasure Coast experience in 2014 took place over a brief 18-hour period.

She first pinged offshore of the Sebastian Inlet at 7:27 a.m. May 12. At 5:01 p.m., she swam in as close as The Monster Hole on the south side of the inlet, which is about a quarter-mile off the beach.

The next morning, she headed into deeper water. By 6 p.m. May 13, she checked in at about 40 feet of water off the St. Lucie Inlet. Her next ping wasn’t for about 42 hours, and it was off the Boynton Beach Inlet.

She then pinged in along the Florida Keys before entering the Gulf of Mexico. She spent June gaining more fans in the Gulf before swinging back south and heading toward Sarasota, where she pinged about 60 miles offshore at 7:11 a.m. July 6.

Katharine went silent for 11 days before she was pinged July 17 off Key Largo, but she didn’t stick around. By 11:28 a.m. July 21, she pinged about 30 miles off Ormond Beach, covering about 337 miles in four days.
