Rain continues to pound southwestern Connecticut this afternoon, with heavier downpours inundating the region after midday.

The National Weather Service warns the wind-whipped rain could spark flooding. Winds are gusting to nearly 50 mph, which also poses a threat to power lines and tree limbs.

However, power outages are scattered so far in the Fairfield-Westport area. As of about 3 p.m., United Illuminating reported only four customers had lost electric service, while Northeast Utilities said 33 had lost power in Westport.

The weather service warns there also may be a line of thunderstorms sweeping through the region later this afternoon.

Despite the otherwise miserable conditions, the day is relatively mild with the 3 p.m. reading at 59 degrees.

Showers are expected to continue into evening, with gradual clearing and an overnight low around 37 degrees.

Thursday's forecast appears to be a little brighter -- sunny, with a high near 43.
