The Storm Watch Team is tracking the coastal storm that is expected to pound Connecticut overnight with heavy rain and wind.
NATIONAL WEATHER SERVICE ALERTS:
Flood Watch | All of western CT | Through Monday afternoon
This highlights the potential of road, stream and creek flooding during this time. 
Coastal Flood Warning | Shore | Through Sunday 10 p.m. to Monday 6 p.m.
This covers the high tide Sunday night and then the Monday afternoon one. 
The Sunday night high tide will be minor flood stage. Less than one foot of salt water on normally dry roads will be likely. This will be more of a nusicance than anything else.
The Monday afternoon high tide will be in moderate flood stage. Property threatening flood will be likely here. Up to 18" of salt water will be likely in any one location near the tidal waters. Numerous road closures will be likely. Drivers could stall their cars on the roads driving through it. 
High Wind Warning | South of the Merritt Parkway | 12 a.m. to 12 p.m. MondayThis highlights the risk of downed trees and power lines, creating outages. Traveling on bridges and in high profile vehicles will be difficult. 
Wind Advisory | North of the Merritt Parkway | Sunday evening to 7 a.m. Monday
This highlights the risk of spotty power outages and wind damage to large tree branches and tree limbs. 
PUSH ALERTS: CT's multi-impact storm is strengthening now. Wind, rain and tidal flooding will all be likely. Meteorologist Joe Martucci has more on News 12 at 6 p.m.
NEW: Rain becomes heavier and steadier. Winds will continue to pick up into the evening. The worst of the storm will be from roughly 1 to 9 a.m. Monday. A driving, wind-swept rain will create some issues on the roads. Streams and creeks can rise above their banks. Fortunately, last week's storm had minimal issues with the heavy rain. Despite nearly the same rain this time, I expect more issues, as the ground is already saturated. Coastal flooding will occur, likely closing some roads. After 9 a.m. Monday, expect a break. However, another 2-3 hours of rain will pass between 11 a.m. and 5 p.m. Winds will remain gusty, though not enough for any serious wind issues. One more round of coastal flooding will occur when it rains, too.NEXT: Winds will stay breezy Monday night through Tuesday, but not as serious as Sunday night - Monday morning. A few rain or snow showers will be possible from the pre-dawn to mid-morning Tuesday north. If it's dry then, it'll be dry until at least Friday. Temperatures will be more seasonable. 
FORECAST: Sunday Night: Wind swept rain. Rain and tidal flooding will threaten. Damaging winds will not be ruled out. Temperatures rise through the 50s.
Monday: Heavy rain and strong winds until roughly 8AM. Then, gusty winds continue with a break in the rain until late morning. Another round of rain will be present through late afternoon. Temperatures fall into the 50s and 40s.  Monday Night: Clear to start with a cold wind. Mixed rain/snow showers will be possible toward dawn. Lows in the upper 20s to around 32. Tuesday: A rain/snow shower possible until 10AM. Otherwise, intervals of sun and cold. Breezy. Highs around 40F, with wind chills below 32. Wednesday-Friday: Plenty of sunshine. Morning lows in the 20s. Highs will be 40-45F
