A Flash Flood Watch and a High Wind Watch will be in effect Sunday as a nor'easter could bring strong wind gusts, some flooding, and a couple of inches of rain.

A new tropical stem developed Saturday, although it is not projected to affect the city as a tropical system; its moisture will instead combine with a cold front to create a nor'easter.

New Yorkers can expect periods of heavy rain, for an accumulation of 2 to 4 inches, with high rainfall amounts in some parts of the city.

The Flash Flood Watch will be in effect Sunday at noon until 6 a.m. Monday, which may result in flooding in some streets and low-lying areas of the city. The strongest showers and wind are slated to arrive in the afternoon and evening hours.

A High Wind Watch will be in effect from 6 p.m. Sunday until 6 a.m. Monday, with wind gusts possibly reaching 45 to 55 mph. The high should be 67 degrees.

The nor'easter is slated to hit the city on the five-year anniversary of Hurricane Sandy.

A few more showers are forecast for Monday morning, and the wind will linger.

But for Halloween on Tuesday, the city is slated to be drier and brighter, with daytime temperatures in the upper 50s.
