POTENTIAL FOR HEAVY RAIN AND FLASH FLOODING LATER TODAY THRU THE DAY ON WEDNESDAY

FLOOD WATCHES ISSUED... The National Weather Service has issued Flood Watches for most of the state (except Windham and New London Counties) from 2:00 PM this afternoon until 8:00 PM tomorrow evening.

STORM SCENARIO... Some scattered thunderstorms are expected this afternoon in Western CT which may contain heavy rain, however, the main storm impact is expected tonight and Wednesday.

Tonight, a slow-moving low-pressure system is forecast to form in Pennsylvania and move very slowly to the east Wednesday morning. This moisture packed low is forecast to push a wide area of heavy rain into our area tonight and into the day on Wednesday.

MODERATE RISK OF EXCESSIVE RAINFALL... The NOAA Storm Prediction Center has placed Western Connecticut, Southeastern New York and Northern New Jersey into the Moderate Risk Category for excessive rainfall on Wednesday. Central CT is in the Slight Risk and Eastern CT is in the Marginal Risk Category
Moderate risk is fairly rare and towns, especially in Western CT are advised to closely monitor their areas for heavy rainfall and flooding during the next 36 – 48 hours.

TOTAL RAINFALL FORECASTS... The short-range high-resolution models (UK, NAMHRES and HRRR) are still in disagreement on the location of the heaviest bands of rainfall. All three models are indicating that a band of 3” – 6” of rain will form either in Southeastern New York or Western CT. Within this band, training of thunderstorms could generate much higher rainfall amounts of 5” – 10”. It’s not possible to determine the exact location of the heaviest bands until they develop tonight and into the day on Wednesday.

Hazards Expected The primary threat from this storm is expected to be from heavy rainfall (rates of 1” – 2” per hour). The most vulnerable locations are expected to be in urban areas and along streams and moderate sized rivers such as the Housatonic, Quinnipiac and Farmington. No significant threat of severe weather is expected.

APPROXIMATE HEAVY RAINFALL TIMING... Shown to the right is a forecast from the HRRR model showing the expected up and down intensity of the rainfall over the next 36 hours. Another aspect of this storm may be orographic lifting which is the tendency for the heaviest rain to occur on the eastern sides of hills as moisture is pushed into our area from the southeast.

07/21/2026

Current radar is showing a cluster heavy showers and hunderstorms approaching Fairfield county. Rainfall rates within these storms may reach 4 inches per hour in a few towns.

This cluster is moving slowly and towns in the path of these storms need to prepare for some urban and small stream flooding.

NOAA’s Weather Prediction Center has placed the entire state and southern New England into the Slight Risk Category for excessive rainfall today.

Slight Risk is defined as a 15% chance for excessive rainfall within 25 miles of any point within the slight risk area. NOAA’s Weather Prediction Center has placed western Connecticut into the Slight Risk Category for severe thunderstorms later today.

The SPC is forecasting that any thunderstorms that develop will have a 15% chance for strong winds, 5% for tornadoes and a 5% chance for large hail. The highest risk for all three hazards is in western CT.

The most likely period for severe thunderstorms is from 2:00 – 9:00 PM.

07/05/2026

The State of CT Dept of Homeland Security and Emergency Management sent out this information regarding the 36 hour rain event beginning this evening.

HEAVY RAINFALL AND FLASH FLOOD POTENTIAL UPDATE
FLOOD WATCHES ISSUED FROM NOW THRU TUESDAY MORNING
FLOOD WATCHES HAVE BEEN ISSUED FOR ENTIRE STATE BEGINNING TODAY AND CONTINUING INTO EARLY TUESDAY AFTERNOON. A PROLONGED PERIOD OF SHOWERS AND THUNDERSTORMS ARE EXPECTED IN OUR AREA FOR THE NEXT 36 HOURS.

EXCESSIVE HEAT AND HUMIDITY DURING THE PAST WEEK HAVE GENERATED A DEEP LAYER OF VERY HUMID AIR OVER THE EASTERN U.S (BLUES AND PURPLES ON THIS MAP). SEVERAL MODELS ARE FORECASTING THAT A CONVERGENCE ZONE BETWEEN HIGH PRESSURE TO OUR NORTHEAST AND A WEAK LOW PRESSURE SYSTEM IN THE OHIO VALLEY WILL SET UP OVER NEW YORK AND SOUTHERN NEW ENGLAND FOR THE NEXT 36 HOURS.

NOAA’S WEATHER PREDICTION CENTER HAS UPGRADED SOUTHERN CONNECTICUT INTO THE MODERATE RISK CATEGORY (LEVEL 3 OUT OF 4) FOR EXCESSIVE RAINFALL ON MONDAY. LIKE THE RISK OF SEVERE THUNDERSTORMS, THE MODERATE RISK CATEGORY FOR EXCESSIVE RAINFALL IS NOT ISSUED VERY OFTEN. MODERATE RISK IS DEFINED AS A 40% CHANCE FOR EXCESSIVE RAINFALL LEADING TO FLOODING WITH 25 MILES OF ANY POINT WITHIN THE RISK AREA.

AS VERY HUMID AIR IS PUSHED UP INTO NEW ENGLAND THIS EVENING FROM THE SOUTHWEST, MODELS ARE INDICATING THAT A WIDE BAND OF MODERATE TO HEAVY RAINFALL WILL DEVELOP ACROSS SOUTHERN NEW ENGLAND. WITHIN THIS BAND, SHOWERS AND THUNDERSTORMS MAY DEVELOP OVER OUR AREA. THESE SLOW-MOVING SHOWERS AND THUNDERSTORMS
MAY CONTAIN VERY HEAVY RAINFALL (RAINFALL RATES OF 1” – 2+” PER HOUR) AND MOVE REPEATEDLY FROM WEST TO EAST OVER THE SAME AREA.

REPEATED ROUNDS OF SLOW-MOVING SHOWERS AND THUNDERSTORMS COULD ACCUMULATE A GENERAL 3” – 5” OF RAINFALL ACROSS OUR AREA OVER THE NEXT 36 HOURS. RIVERS AND STREAMS CAN HANDLE 5” OF RAINFALL WITHOUT ANY SIGNIFICANT FLOODING AS LONG AS THE RAINFALL IS SPREAD OUT OVER A 24 – 36 HOUR PERIOD.

HOWEVER, IF SHOWERS AND THUNDERSTORMS CONCENTRATE OVER LOCAL AREAS AND DELIVER REPEATED ROUNDS OF VERY HEAVY RAINFALL, TOWNS COULD SEE LOCALIZED AMOUNTS IN SOME NARROW BANDS OF WELL OVER 6” (CURRENTLY BEING FORECAST BY THE NAMHRES MODEL SHOWN TO THE RIGHT).
SINCE IT’S NOT POSSIBLE TO FORECAST THE EXACT LOCATION OF THE HEAVIEST RAINFALL IN ADVANCE, TOWNS ARE STRONGLY ADVISED TO MONITOR THEIR LOCAL WEATHER CONDITIONS.
THIS EVENT HAS SOME SIMILARITY TO THE AUGUST, 18TH , 2024 FLOODING EVENT. THEREFORE, TOWNS SHOULD CLOSELY MONITOR ANY DEVELOPING LINES OR CLUSTERS OF

THUNDERSTORMS FOR THE NEXT 36 HOURS. IF STORMS BEGIN TO STALL OR REPEATEDLY MOVE OVER THE SAME AREA, TOWNS NEED TO BE PREPARED TO ACT QUICKLY IF SIGNIFICANT TO MAJOR URBAN FLOODING OCCURS.

SHOWN TO THE RIGHT IS ONE MODEL (NAMHRES) FORECAST OF HOW HEAVY THE RAINFALL WITHIN THUNDERSTORMS MAY BECOME OVER THE NEXT 36 HOURS. SOME THUNDERSTORMS COULD CONTAIN RAINFALL RATES UP TO 2.5 INCHES PER HOUR. THE NAMHRES IS INDICATING THAT THE HEAVIEST RAINFALL ASSOCIATED WITH THUNDERSTORMS MAY OCCUR MONDAY AFTERNOON INTO MONDAY EVENING.

HOWEVER, DIFFERENT MODELS HAVE DIFFERENT TIMING SO TOWNS SHOULD NOT LET THEIR GUARD DOWN. TOWNS SHOULD CLOSELY MONITOR THUNDERSTORMS REGARDLESS OF WHEN THEY FORM.

07/05/2026

The National Weather Service has a nnounced a Flood Watch is in effect from this afternoon through Monday night. Multiple rounds of heavy showers and thunderstorms. We expect over three inches of rain in Old Saybrook during the period.

Extreme Heat Wave Scenario...

A large Bermuda High is forecast to become anchored off the east coast this week. Heat and humidity are expected to push into New England as a very hot air mass circulates up the east coast.
Bermuda Highs are common during the summer, however, this high is forecast to push near record heat and humidity into our area this week.

Extreme Heat Warnings Issued for Connecticut

Extreme Heat Warnings have been issued for most of the state except for Litchfield, New London and southern Middlesex County where Extreme Heat Watches remain in effect.

An air quality alert has also been issued by the DEEP for areas within Hartford, Fairfield, New Haven and Middlesex counties for today.

Temperature and Heat Index Forecast...

Forecasts are currently indicating that our area will see a 6-day heat wave starting today.

Very hot and humid air is expected to move into the state over the next 24 hours and continue into the holiday weekend.

Thursday and Friday are currently expected to be the hottest and most humid days.

The Heat Indices (a combination of hot temperatures and high humidity) are expected to be the highest in urban centers located inland from the coast. The cities of Hartford, Danbury, Waterbury and New Britain may approach heat index values of 100 - 105 F on Wednesday. The coastal cities of New Haven and New London may benefit from a light sea breeze.

The Heat Indices are expected to be higher on Thursday. The highest heat indices are expected in urban centers located inland from the coast. The cities of Hartford, Danbury, Waterbury and New Britain may approach heat index values of 100 - 110 F on Thursday. The coastal cities of New Haven and New London may benefit from a light sea breeze.

The Heat Indices are expected to be nearly the same on Friday. The highest heat indices are expected in urban centers located inland from the coast. The cities of Hartford, Danbury, Waterbury and New Britain may approach heat index values of 100 - 110 F on Friday. The coastal cities of New Haven and New London may benefit from a light sea breeze.

The Heat Indices are expected to be almost as high on Saturday. The highest heat indices are expected in urban centers located inland from the coast. The cities of Hartford, Danbury, Waterbury and New Britain may approach heat index values of 100 - 105 F on Saturday. The coastal cities of New Haven and New London may benefit from a light sea breeze.

Afternoon Thunderstorms Possible Each Day...
The heat and humidity may trigger pop-up thunderstorms each afternoon during the heat wave. Any thunderstorms that form may contain gusty winds, dangerous lightning, hail and torrential downpours. The risk for tornadoes is expected to be very low.

Hot Weather Safety...
Although anyone can suffer from heat-related illnesses, some people are at greater risk than others:
1. Infants and young children are sensitive to the effects of high temperatures and rely on others to regulate their environments and provide adequate liquids.
2. People 65 years of age or older may not compensate for heat stress efficiently and are less likely to sense and respond to change in temperature.
3. People who are overweight may be prone to heat sickness because of their tendency to retain more body heat.
4. People who overexert during work or exercise may become dehydrated and susceptible to heat sickness.
5. People who are physically ill, especially those with heart disease or high blood pressure, or who take certain medications, such as those for depression, insomnia, or poor circulation, may be affected by extreme heat.

Hot Weather Tips...
1. Keep your body temperature cool to avoid heat-related illness.
2. Stay in air-conditioned buildings as much as possible. If you must be outdoors, try to limit your outdoor activity to the morning and evening. Try to rest often in shady areas so that your body has a chance to cool off.
3. Find an air-conditioned location. (Call 2-1-1 for a list of cooling centers.) Do not rely on a fan as your primary cooling device.
4. Avoid direct sunlight.
5. Wear lightweight, light-colored clothing.
6. Take cool showers or baths.
7. Check on those most at-risk several times a day.
8. Pets that cannot be brought indoors should be provided ready access to water and shade to keep them cool.
9. Never leave pets inside of parked vehicles because temperatures can soar to life-threatening levels within minutes.

Hot Weather Tips...

Stay Hydrated: Because your body loses fluids through sweat, you can become dehydrated during times of extreme heat

1. Drink more water than usual.
2. Don’t wait until you’re thirsty to drink more fluids.
3. Drink from two to four cups of water every hour while working or exercising outside.
4. Avoid alcohol or liquids containing high amounts of sugar.
5. Remind others to drink enough water

Although anyone can suffer from heat-related illness, some people are at greater risk than others: ● Infants and young children are sensitive to the effects of high temperatures and rely on others to regulate their environments and provide adequate liquids. ● People 65 years of age or older may not compensate for heat stress efficiently and are less likely to sense and respond to change in temperature. ● People who are overweight may be prone to heat sickness because of their tendency to retain more body heat. ●People who overexert during work or exercise may become dehydrated and susceptible to heat sickness. ● People who are physically ill, especially those with heart disease or high blood pressure, or who take certain medications, such as for depression, insomnia, or poor circulation, may be affected by extreme heat.
Some prevention tips to stay safe in extreme heat include: ● Keep your body temperature cool to avoid heat-related illness. ● Stay in air-conditioned buildings as much as possible. If you must be outdoors, try to limit your outdoor activity to the morning and evening. Try to rest often in shady areas so that your body has a chance to cool off. ● Find an air-conditioned location.

Everyone is also reminded to stay hydrated during periods of extreme heat. As we lose fluid through sweat, dehydration is common during very high temperatures. It is strongly encouraged to: ●Drink more water than usual. ● Don’t wait until you’re thirsty to drink more fluids. ● Drink two to four cups of water every hour while working or exercising outside. ● Avoid alcohol or liquids containing high amounts of sugar. ● Remind others to drink enough water.
