FLHurricane.com: Serious Flood Threats: New England Henri and Hawaiian Linda

11PM EDT 23 August 2021 Update
Henri is now Post-Tropical Depression Henri and pushing out to sea, at last.

"Former" Tropical Storm Linda is presently crossing the northern Hawaiian Islands producing locally heavy rain and sustained winds at or near Tropical Storm Force, with higher gusts. Flash Flood Watches and Wind Advisories remain in effect.

Elsewhere, we are quickly turning attention to three features in the Atlantic basin that have medium and rising odds of developing into Tropical Cyclones this week. 2021 Forecast Lounges are now open on all three of these systems, and a new Main Page thread is probably just around the corner.

2PM EDT 22 August 2021 Update
Flood threats continue to be the theme today with also Central Pac Linda now on approach to the Hawaiian Islands looking at least sufficiently organized to necessitate Flood Watches for the entire chain. Tropical rains capable of producing flash flooding are expected to start soon over the Big Island today and spread across much of the rest of the state throughout the day today into Monday night.

We have opened a Linda Forecast Lounge Model runs are still actively tracking the system, and given recent satellite trends, it would not surprise to find it a Tropical Cyclone yet again.

1PM EDT 22 August 2021 Update
Henri has made landfall along the coast of Rhode Island at around 12:15PM EDT with maximum sustained winds at time of landfall estimated to be around 60 MPH and with a central pressure of 989mb. Continued weakening is expected as the now Tropical Storm Henri continues north-northwestward with forward speed continuing to slow, and bend even further to the west, to perhaps outright stalling near the New York/Connecticut border tonight.

Original Update
HURRICANE HENRI STRENGTHENING HEADING TOWARDS LANDFALL

Now Hurricane Henri is on approach to an almost certain direct landfall along the Northeastern US coast between upper New Jersey and Providence, R.I. This is a rare occurrence, and many who live here have not experienced a hurricane for many years, if at all.

Recon is now finding that Hurricane Henri is definitely intensifying tonight, and he may even come in notably above forecast. Regardless, in addition to strong winds and storm surge, there is even greater potential for the forward speed of the cyclone to slow down near or soon after landfall, creating a long duration coastal and inland flood threat, and one that is potentially locally catastrophic in some places.

Preparations to protect life and property should be nearing completion as conditions starting as soon as late tonight and spreading in tomorrow and tomorrow night could prevent them from being done at that time, and also prevent first responders from providing aid.
