    Mesoscale Discussion 0490 NWS Storm Prediction Center Norman OK 1252 PM CDT Tue May 22 2018 Areas affected...Northeastern Virginia...southern Maryland...and the District of Columbia Concerning...Severe potential...Watch possible Valid 221752Z - 221945Z Probability of Watch Issuance...60 percent SUMMARY...Damaging wind gusts will be possible with stronger storms this afternoon. DISCUSSION...A relatively cloud-free area on visible satellite imagery has been persistent throughout the morning into early afternoon. This has allowed surface temperatures to rise into the mid- to upper-70s. With ample surface moisture -- dewpoints generally in the mid- to upper-60s -- MLCAPE values are currently near 1000 J/kg. With time, continued surface heating should further destabilize the area. Shear values are relatively modest with values between 25-30 kts; however, particularly in areas that receive the most insolation, low-level lapse rates may support damaging wind gusts. Visible satellite imagery indicates weak convection occurring to the west of the discussion area. These storms should intensify as they move into a move favorable environment east of the Appalachians. ..Wendt/Elliott/Weiss.. 05/22/2018 ...Please see www.spc.noaa.gov for graphic product...

    Special Weather Statement National Weather Service Mount Holly NJ 854 PM EDT Tue May 15 2018 DEZ004-NJZ014-024>026-161200- Delaware Beaches-Eastern Monmouth-Atlantic Coastal Cape May- Coastal Atlantic-Coastal Ocean- Including the cities of Rehoboth Beach, Sandy Hook, Ocean City, Atlantic City, and Long Beach Island 854 PM EDT Tue May 15 2018 ...Abnormal ocean water surges are expected along the oceanfront, inlets, and back bays through the overnight hours... Air pressure sensor and tidal gage readings in and near the coastal waters indicate that a weather-generated tsunami has been triggered by the line of thunderstorms as it moved over the ocean. Impacts are expected along the oceanfront, inlets, and back bays from Perth Amboy New Jersey to Fenwick Island Delaware. Water level fluctuations of several inches to one foot above normal astronomical tide in localized areas can be expected along the oceanfront, inlets, and back bays for the next several hours as a series of surges make their way to the coast. The duration of this event is uncertain, though similar events have lasted from several hours to one day. It is not recommended to return to the water until at least Wednesday morning. The strong currents associated with these surges could pose a danger to those in or near the water. Recommended actions are listed below... Boat Owners... Prepare now for the following hazards... * Strong, unpredictable currents * Surging up to one foot above normal sea level Swimmers...Surfers...and Boaters It is recommended you leave the beach now to avoid the following hazards... * Strong currents * Potentially dangerous surges of water. This kind of tsunami is generated by abrupt changes of atmospheric pressure in the causative storm system, which is a line of thunderstorms that moved over the ocean in this case. The combination of the air pressure effect on the ocean surface and the speed at which the pressure disturbance travels can generate tsunami like waves in certain situations. The National Tsunami Warning Center is monitoring this event. Additonal statements will be issued if necessary through National Weather Service Office Forecast Office in Mount Holly, NJ.
