Weather Alert in New York
Coastal Flood Watch issued February 20 at 4:27PM EST until February 23 at 4:00AM EST by NWS Upton NY
AREAS AFFECTED: Southwest Suffolk; Southern Nassau
DESCRIPTION: * WHAT...1 1/2 to 2 1/2 ft, locally 3 ft, of inundation above ground level possible in vulnerable areas near the waterfront and shoreline. * WHERE...Southwest Suffolk and Southern Nassau Counties. * WHEN...From Sunday evening through late Sunday night. * COASTAL FLOOD IMPACTS...Widespread moderate flooding of vulnerable areas near the waterfront and shoreline possible. Expect 1 1/2 to 2 1/2 ft, locally 3 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 the ocean front will cause widespread beach flooding and erosion during the time of high tide. Areas of dune erosion are likely, with localized washovers possible where dunes are compromised. * 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.

Similar to cirrocumulus clouds, altocumulus clouds are
characterized by cloud patches. They are distinguished by larger cloudlets
than cirrocumulus clouds but are still smaller than stratocumulus clouds.
Altocumulus clouds most commonly form in middle altitudes (between 2 and 5 km)
and may resemble, at times, the shape of a flying saucer.
These uncommon formations, called altocumulus lenticularis, are created by uplift
in the atmosphere and are most often seen in close proximity to mountains.

Cirrocumulus clouds form at high altitudes (usually around 5 km)
and have distinguishing characteristics displayed in a fine layer of
small cloud patches. These small cloud patches are sometimes referred to as
"cloudlets" in relation to the whole cloud formation.
Cirrocumulus clouds are formed from ice crystals and water droplets. Often, the
water droplets in the cloud freeze into ice crystals and the cloud becomes a
cirrostratus cloud. Because of this common occurrence, cirrocumulus cloud
formations generally pass rapidly.
