With a strong nor’easter expected late Thursday and Friday, the National Weather Service has posted a flood and high wind watch and a coastal flood advisory.

The nor’easter will bring several inches of rain, pack strong winds and drop a few inches of heavy, wet snow across northern areas of the state.

The rain that is expected to begin Thursday evening, will end Saturday morning.

It’s possible it could cause some power outages and make for a tough Friday morning and evening commutes.

“A deepening coastal low late Thursday night into Friday will bring heavy rain across the area, with the potential for 2 to 3 inches of rainfall.” the NWS says. “Heavier bands could produce localized higher amounts. Smaller rivers and streams across the area will be most vulnerable to the possibility of flooding.”

Here’s what you need to know.

NWS update, Friday evening

Wind gusts ranging from 50 to 70 mph are expected. Strongest winds will hit Friday night, but will fade after midnight.

The weather service said damaging winds will be capable of downing trees and power lines, resulting in power outages. Thousands in Fairfield County remain without power Friday as of 6:15 p.m.

Travel will be difficult Friday night for vehicles with high profiles.

Coastal flood advisory in effect Saturday to Sunday

The National Weather Service issued a coastal flood advisory in effect from 10 a.m. Saturday to 2 a.m. Sunday. The coastal flood watch is no longer in effect.

Vulnerable locations are along the Long Island Sound in southern Connecticut. Tides are expected to be two-and-a-half feet to three feet above normal.

“Minor to locally moderate coastal flooding expected with the high tides through Saturday night,” the NWS advisory said.

This weather, along the coast, may cause road closures and widespread minor flooding. Cars parked near the waterfront could be flooded, the NWS said.

The rain

Current rainfall forecasts include 2.25 inches for southwestern Fairfield County and between 1.75 and 2.5 inches for the rest of Connecticut.

Rain is expected to begin after 7 p.m. on Thursday.

The NWS’s hourly forecast says the best chance of rain is between 9 p.m. Thursday to 8 p.m. Friday.

The snow

Northern Connecticut and higher elevation areas could get some snow from the backside of the storm.

Little, if any, snow accumulation is expected along the shoreline. Snowfall totals on the cost are around less than one inch.

The NWS says the Danbury and Waterbury areas could see anywhere from 2 to 3 inches.

Torrington and into the Northwest Hills could have between 3 and 4 inches.

The best chance of snow is between 6 a.m. to 8 p.m. Friday.

The wind

The high wind watch is in effect from Friday afternoon through Friday night.

Wind will be whipping from the north between 25 to 40 mph with gusts up to 60 mph.

Strongest winds are expected from 5 p.m. Friday to 2 a.m. Saturday.

Southeast Connecticut is under a high wind warning. Damaging winds will be capable of downing trees and power lines. Power outages are possible.

Travel will be difficult, especially for high profile vehicles. Limited visibilities will make travel difficult.

Coastal flooding

Southern Fairfield and New Haven counties have a coastal flood advisory from 10 a.m. to 1 p.m. Friday.

Shallow flooding is expected in the most vulnerable locations near the waterfront and shoreline.

Expect around 1 to 2 feet of inundation above ground level in low lying, vulnerable areas.

Tide times here.

Some roads and low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront will experience shallow flooding.

Temperatures

Thursday’s high temperature will be in the mid-50s.

On Friday, it will be colder with temperatures dropping into the mid to upper 30s.

Because of strong winds, it will feel like 25 to 30 degrees during the day on Friday.

Sunday’s temps will peak in the low to mid-40s.

Friday commute

With heavy rain falling, strong winds and an increased chance of snow farther inland, there will be likely some travel issues during the morning and afternoon commute.

Power outages

The strong winds along the shoreline could cause power outages from fallen trees and limbs.

Inland where heavy, wet snow is expected more widespread outages could happen.

Eversource says its line and tree crews are ready to respond as a powerful nor’easter moves into the region, bringing strong winds, heavy rain and wet snow. With wind gusts of up to 60 mph, this storm has the potential to bring trees and tree limbs down onto power lines, causing damage to the energy system.

“We continue to closely monitor the weather forecast. The heavy rain and snow expected will further saturate the ground and weaken trees, leaving them susceptible to come down in high winds,” said Eversource Vice President of Electric Operations Mike Hayhurst. “We have hundreds of employees ready to respond and will have crews prepositioned around the state well before the storm hits so we’re there when customers need us to safely and quickly restore power after an outage.”

The company reminds customers to always stay clear of downed wires and to report them immediately to 9-1-1. They can report an outage online at www.eversource.com, or by calling 800-286-2000. Those who signed up for the company’s two-way texting feature can send a text to report an outage and receive outage updates as they happen.
