08/23/21 10:30 AM: FLOOD WATCH ISSUED FOR ALL THE STATE TODAY. HENRI’S REMAINS ARE EXPECTED TO GENERATE VERY HEAVY RAIN AND URBAN / SMALL FLOODING TODAY. At 10:00 am, the satellite and radars show the altitude rotation of Henri’s remains centered over eastern New York State. Bands of heavy showers are already occurring in the Bridgeport and Hartford areas. Many small streams and rivers are currently ½ to ¾ full. Temperatures are currently in the low to mid-1970s statewide with a very humid air mass over our area. The soil remains fully saturated by yesterday’s tropical rainfall across the state.

In this very humid atmosphere, any daytime heating is likely to trigger the development of very heavy showers and some thunderstorm activity. The showers and thunderstorms that develop can contain precipitation of up to 2 inches per hour. These torrential downpours will quickly cause urban flooding and small streams. The slow movement of Henri’s remains can also lead to streaks of heavy rain remaining over the same towns that have the potential to deliver up to 3 inches of rain in just a few hours. As in all endangered tropical systems, an isolated weak tornado cannot be excluded.

The formation of these heavy showers and a few thunderstorms is expected to start around noon and peak between 3:00 p.m. and 6:00 p.m. with the maximum warming of the day. The time of the heaviest precipitation may coincide with the afternoon rush hour, causing significant puddling on the roads and moderate impact on rush hour. Heavy showers are expected to ease this evening after sunset. Total precipitation is expected to range from 1 “to 3” statewide with the potential for locally higher amounts.

UPDATE from 08/23/21 at 9:30 a.m. Parker Bridge is now open. With rain coming today and tonight, the bridge could close. 08/23/21 – 8:00 am update: Parker Bridge is CLOSED due to flooding. Please do not use flooded roads and DO NOT bypass barriers.

August 21, 2021 – 11:00 AM – HENRI BECOMES A HURRICANE… LAST TRACK SLIGHTLY EASTWARD WITH A PLANNED LANDING NEAR MADISON AT 8:00 PM SUNDAY EVENING. For this afternoon, Henri is expected to continue ascending the east coast of the United States, remaining 200 to 300 miles offshore. Henri is expected to continue to gradually strengthen this afternoon as the storm moves through the warm waters of the Gulf Stream east of Carolina and Virginia. Henri’s first effects are now expected to begin between 6:00 a.m. and 10:00 a.m. Sunday morning. Wind and rain are expected to increase steadily in the late morning and throughout the afternoon. Henri is expected to make landfall near Madison, CT on Sunday evening between 6:00 PM and 7:00 PM as a strong tropical storm with sustained winds of 70 MPH and gusts to 85 MPH.

Moderate to major coastal flooding will be expected. Moderate river and major urban flooding expected: Henri is expected to bring 4 “to 8” + of precipitation statewide, which is likely to cause moderate to major urban flooding and moderate flooding to rivers and streams on Sunday afternoon and evening.

Moderate to severe damage to trees and power lines expected: Winds can gust to 65 to 85 MPH at times over south-central and southeastern CT on Sunday afternoon and in the evening with wind gusts of 40 to 60 MPH in the rest of the state. These wind speeds could cause significant damage to trees and power lines across the state.

Prepare for power outages that can last for several days. If you are using electrically powered medical devices, make sure you have a back-up device such as a generator or a place to go with electricity or multiple back-up oxygen tanks. Have a plan before the emergency !! Drinking water will be available at the town hall from Monday.

Please do not use flooded roads and DO NOT bypass barriers. Please pay special attention to the Flanders River Road, the Hop River Bridge and the Parker Bridge. TURN, DON’T DROWN!

Flood Safety Information:

  • Monitor the NOAA Weather Radio or your favorite news source for vital weather information. In the event of a flood, go to higher ground.
  • Get out of areas prone to flooding. This includes hollows, low points, drainage ditches, canyons, washouts, etc. Avoid areas that are already flooded, especially if the water is flowing quickly. Do not try to cross waterways. Turn around, don’t drown ™
  • Platforms can be washed away by flood water. NEVER drive on flooded roads – you don’t know the condition of the road underwater. Turn around, don’t drown ™
  • Do not camp or park your vehicle along streams and lakes, especially under threatening conditions. Move to higher ground during heavy rains or rising waters. Streams and streams can rise very quickly during heavy rains.
  • Be especially careful at night when it is more difficult to recognize the dangers of flooding.
  • If you must evacuate your home, secure your home and, if possible, shut off utilities at main switches or valves if requested. Unplug electrical appliances. Do not touch electrical equipment if you are wet or standing in water.
  • Do not walk in moving water. Six inches of moving water can knock you down. If you must walk in the water, walk where the water is not moving. Use a stick to check the firmness of the ground in front of you.
  • Do not drive in flooded areas. If floodwaters are rising around your car, abandon the car and move to higher ground if it is safe to do so. You and the vehicle can be swept away quickly.
  • Six inches of water will sink to the bottom of most passenger cars, causing loss of control and possible stalling.
  • A foot of water will float many vehicles.
  • Two feet of white water can take most vehicles, including sport utility vehicles (SUVs) and pickup trucks.

Play smart, play smart. Whether by car or on foot, whenever you arrive on a flooded road, TURN ON, DON’T DROWN!
