Tracking Henri: Heavy rain, dangerous floods still possible as storm moves on

Weather

NEW YORK — After pelting New York and New Jersey with massive amounts of rainfall, Henri declined to a tropical depression Sunday night, moving west-northwest at 7 mph with maximum sustained winds of 35 mph.

Although the worst of Henri is over, there are still a few lingering showers to contend with as the storms moves over New England. Damaging winds and storm surge are no longer a threat. However, there could be a thunderstorm along with flash flooding, high surf, and rip currents.

Flash flood warnings remained in effect for parts of the New York area.

Additional widespread rainfall amounts of 2 to 5 inches are possible across the Lower Hudson Valley, northeast New Jersey, New York City, inland southern Connecticut, and western Long Island, through Monday evening.

With the ground already saturated, a flood watch will continue through Monday.

Record rainfall has also been an ongoing theme.

Flooding in New York and New Jersey had become the chief concern by Sunday as heavy rain from Tropical Storm Henri pelted the tri-state area.

Heavy rain was expected to continue across the tri-state area through Sunday night and into Monday as the most powerful part of the storm exits the region. The downpours could cause flooding and flash floods over the next 12 to 18 hours.

Heavy rain from Henri caused significant rainfall totals across the region, as of Sunday afternoon:

New York City

  • 7.8 inches in Brooklyn Heights
  • 6.9 inches in Prospect Park
  • 5.2 inches in Battery Park
  • 6.1 inches in Sheepshead Bay
  • 4.3 inches in Flatbush

New Jersey

  • 8.9 inches in Cranbury
  • 8.4 inches in Jamesburg
  • 5.2 inches in Clifton
  • 5.8 inches in Jersey City
  • 4.26 inches in Harrison

Parts of Long Island could possibly up to 6 inches of rain or more. Expect flash flooding from the heavy downpours that will impact the region.

Tidal flooding: Sunday high tides

There will likely be dangerous storm surge of up to 5 feet in some locations. Storm surge-related flooding will be based on the tide cycle. There’s also a full moon, which increases the gravitational pull, which will impact tides. High tides for Sunday are:

  • Battery: 8:55 a.m. and 9:10 p.m.
  • Jamaica Bay: 9:05 a.m. and 9:22 p.m.
  • Sandy Hook: 8:28 a.m. and 8:45 p.m.
  • Jones Beach: 9:49 a.m. and 10:06 p.m.
  • City Island: 12:30 p.m.
  • Bridgeport: 11:54 a.m.

Henri made landfall Sunday on the coast of Rhode Island, and the National Hurricane Center warned that the slow-moving storm would continue dumping heavy rains on wide swaths of the region.
