The National Weather Service says parts of Connecticut could see strong wind gusts between 50 and 70 mph on Monday.
While no warnings or advisories have yet been posted, the NWS issued a Hazardous Weather Outlook early Saturday morning.
It read: “Deep low pressure tracking west of the region will produce strong southerly winds Monday and Monday night. Depending on the ultimate track and intensity of the system, gusts of 50 to 70 mph will be possible, with the strongest winds across Long Island and eastern Connecticut.”
The outlook is for all of southern Connecticut.
A low pressure system — fed by subtropical moisture — is expected to develop Monday and track northeast.
The NWS’ weather discussion gives some highlights of what we could expect:
- “The main focus is on the storm Monday and Monday night; the forecast has been ramped up, particularly with the wind threat.
- “There remains some uncertainty with the amount of rain. This will depend on the setup and orientation of the subtropical moisture feed. There will likely be at least an initial heavy rain burst on Monday, but whether there is more of a prolonged heavy rain threat is still in question.
- “The current forecast is 1-2 inches of rain generally across the area.
- “The system does look poised to produce strong winds. A wind advisory or high wind warning will be needed at some point for portions of the area.
- “The eastern half of the forecast area is most at risk. Right now, expect the threat to be in the range of 50-70 mph gusts, strongest in eastern areas.
- “Some coastal flooding will be possible, but the exact magnitude is very uncertain at this time. The current modeling suggests only minor right now, as the peak winds are lining up with the lower of two astronomical high tide cycles.”
Timing of the storm
The rain:
According to the NWS’s hourly forecast, the most likely period of rain is between 8 a.m. and 6 p.m.
Rain is also “likely” between 7 p.m. and 3 a.m. Tuesday.
A “chance”of rain then continues to 3 p.m. Tuesday.
Southeastern Connecticut has the best chance of a longer period of rain, the NWS says.
The wind:
Peak wind gusts will begin to increase around 11 a.m. and continue into the evening.
Madison on the shoreline could see wind gusts of up to 55 mph.
Stonington could have gusts as high as 59 mph.
Bridgeport could see gusts as high as 47 mph.
Power outages:
Outages are possible with high winds and the fact that the ground has become saturated from recent rain in the last several days.
Any good news?
The storm has the potential to be a drought buster for eastern and southeast Connecticut that still have moderate drought or abnormally dry conditions, according to U.S. Drought Monitor.
