On shortest day of year, a long day of rain, wind

December 21, 2018

Winter officially arrives at 5:23 p.m. on Friday, but it’s going to feel more like April.

Friday is also the shortest - and darkest - day of the year with just 9 hours, 12 minutes of daylight.

Think back to June 21 when we had 15 hours, eight minutes and 42 seconds of daylight.

Friday will feel especially gloomy with rain, heavy at times, throughout the day. There will also be fog, some flooding and gusty winds.

Temperature will be above normal with a high of 62 degrees.

How much rain?

An area of low pressure moving up the spine of the Appalachians will result in a widespread 2 to 3 inch rainfall across the region. Locally higher amounts around 4 inches are possible. Rainfall may be heavy at times.

The latest rainfall projections have the Waterbury getting 2.20 inches, Danbury 2.04 inches, Torrington and the Long Island Sound shoreline 1.86 inches.

Rain is expected to continue most of the day, including the PM commute.

The National Weather Service has posted a number of advisories, watches and warnings associated with this miserable weather.

Flood Watch

The Flood Watch for Connecticut is in effect through late tonight.

“The heavy rain will result in the potential for flooding of urban, low lying, and poor drainage areas. Minor river flooding is expected on fast responding streams. The Passaic River at Pine Brook is forecast to go into moderate flooding tonight. In addition, flooding concerns could be exacerbated along the coast at times of high tide.”

Wind advisory

In effect to 6 p.m. for southern Fairfield and New Haven counties and all of Middlesex and New London counties.

Southeast 25 to 35 mph with gusts 40 to 45 mph. Gusts up to 50 mph possible along the immediate coast through this afternoon.

Strong winds may blow down limbs, trees, and power lines. Unsecured holiday decorations may be damaged or blown away. Scattered power outages are expected.

The NWS hourly forecast has the highest wind gusts between 7 a.m. and 2 p.m.

Coastal flood warning

In effect from 8 to 11 a.m. for southern Fairfield and New Haven counties.

Minor to moderate flooding expected around the times of high tide Friday morning. Minor coastal flooding possible during the times of high tide Friday evening and Saturday morning.

The NWS says, “widespread flooding of vulnerable areas near the waterfront and shoreline. Expect 2 to locally 3 feet of inundation above ground level in low lying, vulnerable areas. This will result in numerous road closures and cause widespread flooding of low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront. Vehicles parked in vulnerable areas near the waterfront will likely become flooded. Flooding will also extend inland from the waterfront along tidal rivers and bays.”
