Weather Alert in New York

Recent Locations: Cincinnatus, NY   Shenorock, NY  

Coastal Flood Watch issued February 20 at 4:27PM EST until February 23 at 6:00AM EST by NWS Upton NY

AREAS AFFECTED: Northeast Suffolk; Southeast Suffolk

DESCRIPTION: * WHAT...1 1/2 to 2 1/2 ft of inundation above ground level possible in vulnerable areas near the waterfront and shoreline. * WHERE...Northeast Suffolk and Southeast Suffolk Counties. * WHEN...From Sunday evening through late Sunday night. * COASTAL FLOOD IMPACTS...Widespread moderate flooding of vulnerable areas near the waterfront and shoreline possible. 1 1/2 to 2 1/2 ft of inundation above ground level possible in low lying, vulnerable areas. This would 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. Ice cover in the bays and harbors could exacerbate flooding and cause damage to northeast to east facing shoreline structures. * SHORELINE IMPACTS...Breaking surf of 4 to 8 ft along Gardiners Bay, particularly Orient Point, will cause beach flooding and dune erosion during the time of high tide. This may also exacerbate splashover flooding of shorelines roads and properties behind protective dunes, structures and seawalls. Minor damage to shoreline structures possible. * ADDITIONAL DETAILS...This water level forecast will be highly dependent on timing of windshift from east northeast to north gales with respect to the time of high tide, and will be refined over the next 24 hours. Ice cover in the bays and harbors could exacerbate flooding and cause damage to northeast to east facing shoreline structures.

INSTRUCTION: If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.

Contrails Next Topic: Cumulonimbus Clouds

A contrail is an artificial cloud, created by the passing of an aircraft.

Contrails form because water vapor in the exhaust of aircraft engines is suspended in the air under certain temperatures and humidity conditions. These contrails are called exhaust contrails.

Another type of contrail can form due to a temporary reduction in air pressure moving over the plane's surface, causing condensation. These are called aerodynamic contrails.

When you can see your breath on a cold day, it is also because of condensation. The reason contrails last longer than the condensation from your breath is because the water in contrails freezes into ice particles.

Cumulus Clouds Next Topic: Drizzle

Cumulus clouds are fluffy and textured with rounded tops, and may have flat bottoms. The border of a cumulus cloud is clearly defined, and can have the appearance of cotton or cauliflower.

Cumulus clouds form at low altitudes (rarely above 2 km) but can grow very tall, becoming cumulus congestus and possibly the even taller cumulonimbus clouds. When cumulus clouds become taller, they have a greater chance of producing precipitation.
