CareConnect, the health insurance unit of Long Island-based Northwell Health hospital group, is pulling the plug on its four-year-old operations, leaving 125,000 enrollees scrambling to find a new insurer, the company announced Thursday.

The company blamed its failure on the fact that it had to pay $112 million—44 percent of its revenue last year—into the Affordable Care Act’s (ACA) risk-adjustment pool that was designed to prevent insurers from “cherry-picking” healthy customers who are less expensive to cover.

“It has become increasingly clear that continuing the CareConnect health plan is financially unsustainable, given the failure of the federal government and Congress to correct regulatory flaws that have destabilized insurance markets and their refusal to honor promises of additional funding,” said Michael Dowling, Northwell’s president and chief executive officer.

The insurer is the second in the New York State of Health insurance marketplace created under Obamacare to be put out to pasture. Health Republic tanked in 2015.

CareConnect will provide the New York State Department of Financial Services with its plan to withdraw from the marketplace as the insurer begins to wind down over the next year, the company said. It will continue to serve members, patients and providers as well as pay claims throughout the transition period, it added. Northwell will help CareConnect’s more than 200 employees find positions elsewhere in the system.

Dowling noted that despite the death of CareConnect, Northwell will continue in its mission to better manage the health of its patients and slow the growth of health care costs.

“The market challenges confronting us require that we continue to be bold in our thinking,” he said. “Moving forward on our population health journey, we will continue to explore new models of care delivery that will help us accomplish the triple aim of improving the patient experience and the health of our communities, and reducing the per capita cost of care.”

The nation’s top weather forecasters are warning that the 2017 Atlantic Hurricane Season is likely to produce more tropical storms and cyclones than they originally predicted shortly before the season started June 1.

Experts with the National Oceanic and Atmospheric Administration (NOAA) said Wednesday that they are upgrading the odds of an above-normal season from 45 to 60 percent since there have already been six named storms—twice as many as typically form by early August.

“We’re now entering the peak of the season when the bulk of the storms usually form,” said Gerry Bell, the lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center. “The wind and air patterns in the area of the tropical Atlantic and Caribbean where many storms develop are very conducive to an above-normal season. This is in part because the chance of an El Nino forming, which tends to prevent storms from strengthening, has dropped significantly from May.”

NOAA initially predicted 11 to 17 named storms, of which 5 to 9 could become hurricanes—including 2 to 4 major hurricanes. The prediction for the number of hurricanes remained the same, but the agency has increased its forecast to 14 to 19 named storms and 2 to 5 major hurricanes.

A storm must have sustained winds of at least 39 mph to be named. For a storm to be declared a hurricane, it must have at least 74 mph sustained winds, the threshold for a Category 1. A major hurricane is defined as a Category 3, which has sustained winds of at least 111 mph, or stronger.

The agency said the season has the potential to become “extremely active,” possibly the most active since 2010. Peak hurricane season runs from mid-August through October. The season ends Nov. 30.

Of the six storms that have formed so far, two hit the US. Cindy made landfall June 22 at the Louisiana-Texas border and Emily struck July 31 in Anna Maria Island, Fla. The updated hurricane forecast comes as Franklin is about to hit Mexico.
