[04/09 AM] Emergency Management Briefing for Coastal Flooding and Winds Thursday
by BOX Operations - NOAA Service Account 09 Apr '20

09 Apr '20

Good morning, No significant changes with respect to the coastal flood threat today. High astronomical tides will pose a risk for pockets of minor coastal flooding around the time of high tide, especially at the typically more vulnerable locations. Gusty west winds are likely behind a departing low pressure this evening. A *Wind Advisory* has been posted for all of Southern New England from 4 PM to 9 PM for west winds which could gust up to 50 mph. *Gale warnings* are posted for most of the southern New England coastal waters late tonight through Friday. If you have any questions or would like more information, don't hesitate to contact us via this email address, on NWSChat <https://nwschat.weather.gov/>, or at the following: National Weather Service Boston/Norton, MA 46 Commerce Way Norton, MA 02766 508.622.3280 Website <http://www.weather.gov/boston> | Facebook <http://www.facebook.com/NWSBoston> | Twitter <http://www.twitter.com/NWSBoston>

[04/08 PM] Emergency Management Briefing for Thursday
by BOX Operations - NOAA Service Account 08 Apr '20

08 Apr '20

Good afternoon, all. No significant changes with respect to the coastal flood threat tonight into Friday. High astronomical tides will pose a risk for pockets of minor coastal flooding around the time of high tides during this time, especially at the typically more vulnerable locations. We may need to extend some Coastal Flood Advisories for the late Friday evening high tide, but confidence is not yet high enough to do so. Gale warnings posted for most of the southern New England coastal waters late Thursday through Friday. There is a possibility for gusty west winds behind a departing low pressure Thursday evening into Friday. Wind Advisories may be issued with later forecasts for gusts of 45 mph or greater. Confidence in gusty winds is high, but only moderate confidence for speeds 45 mph or greater. Please let is know if you require any additional weather information.

[2020-04-08 AM] NWS Boston EM Briefing: Minor Coastal Flooding South and East Coasts
by BOX Operations - NOAA Service Account 08 Apr '20

08 Apr '20

Good morning, Not much has changed with our thinking regarding a period of high astronomical tides the next several days. There will be a risk for pockets of minor coastal flooding today, as well as Thursday into Friday, when a coastal storm makes its closest approach. A long-duration Coastal Flood Advisory has been issued, rather than having the hazards come and go with each tide. Portions of both the east and south coasts of New England are at risk, especially tonight into Thursday night. The link below provides Coastal Flood Threat and Inundation Mapping ... https://www.weather.gov/box/coastal For marine interests, we will likely be dealing with gale force gusts late Thursday into Friday as well. Thank You Bryce Williams and Frank Nocera If you have any questions or would like more information, don't hesitate to contact us via this email address, on NWSChat <https://nwschat.weather.gov/>, or at the following: National Weather Service Boston/Norton, MA 46 Commerce Way Norton, MA 02766 508.622.3280 Website <http://www.weather.gov/boston> | Facebook <http://www.facebook.com/NWSBoston> | Twitter <http://www.twitter.com/NWSBoston>

Weather Hazards Through Friday
by BOX Operations - NOAA Service Account 07 Apr '20

07 Apr '20

Good afternoon, We are heading into a period of high astronomical tides the next several days. While winds will not be very strong tonight through Wednesday, there will be a risk for pockets of minor coastal flooding during this time. A more significant risk for coastal flooding develops late Thursday into Friday, when a coastal storm makes its closest approach. A long-duration Coastal Flood Advisory has been issued, rather than having the hazards come and go with each tide. Portions of both the east and south coasts of New England are at risk, especially Wednesday night into Thursday night. For marine interests, there is also a risk for gale force gusts late Thursday into Friday, also associated with this coastal storm. Please let us know if you have any further questions.

[2020-04-03 PM] NWS Boston EM Briefing: Strong/Damaging Winds, Minor Coastal Flooding for eastern MA, Cape Cod & the Islands
by BOX Operations - NOAA Service Account 03 Apr '20

03 Apr '20

Good afternoon, We've passed the peak of the storm in terms of both coastal flooding and high winds. Below is an update on what remains for tonight into tomorrow morning. *Headlines:* - High Wind Warning*: *Through this evening for Cape Cod, Nantucket, Martha's Vineyard - *Wind Advisory*: Through this evening for the east coast of MA north of Cape Cod - *Coastal Flood Advisory*: In effect for this evening's high tide for Cape Cod, Nantucket, and Martha's Vineyard - *Gale Warning*: Through this evening on all waters. *Details:* *Strong to Damaging Winds:* Winds will slowly diminish through the evening and overnight. Downed trees and power lines will continue to be possible into the evening. *Coastal Flooding: *Minor coastal flooding is possible during high tide this evening for Cape Cod and the Islands. Additionally, Nantucket may still have minor flooding issues with Saturday morning's high tide. *COASTAL FLOOD DEFINITIONS ...* Minor Coastal Flooding - Flooding of the most vulnerable shore roads and/or basements due to height of storm tide or wave splash over. - Majority of roads remain passable with only isolated closures due to nuisance flooding or rip rap. - Isolated inundation up to a foot is possible. - There is no significant threat to life and any impact on property is minimal. - This type of event is covered by a Coastal Flood Advisory.

[2020-04-03 AM] NWS Boston EM Briefing: Strong/Damaging Winds, Minor to Moderate Coastal Flooding for eastern MA, Cape Cod & the Islands
by BOX Operations - NOAA Service Account 03 Apr '20

03 Apr '20

Good morning, Here is the latest update on strong/damaging winds and coastal flooding today across eastern MA. *Changes from previous forecast* ...* High Wind Warning expanded to include Cape Ann (Rockport, Manchester & Gloucester) & Wind Advisory expanded into Boston & into western Plymouth county* *Headlines:* - High Wind Warning*: *In effect from early Friday morning through Friday evening for Cape Cod, Nantucket, Martha's Vineyard and Cape Ann. - *Wind Advisory*: In effect from early Friday morning through Friday evening for Plymouth county to Boston - *Coastal Flood Warning*: In effect for Friday morning's high tide for all of the east coast of MA, including Nantucket and Martha's Vineyard - Storm Warning: In effect early Friday morning thru Friday evening, for the coastal waters east of Ipswich Bay and Stellwagen Bank National Marine Sanctuary and the offshore waters adjacent Cape Cod and the Islands (excluding Buzzards Bay and Vineyard Sound). - *Gale Warning*: In effect early Friday morning thru Friday evening, for the remaining waters. *Details:* *Coastal Flooding: * *Friday Morning: Widespread Minor with pockets of moderate coastal flooding* - *Locations*: entire eastern MA coastline from the NH/MA border to Nantucket. This includes the coastline of Boston, Cape Cod and the Islands. - *Timing*: From 6 AM to 10 AM Friday morning. - *Impacts/Inundation*: For Nantucket: One to two feet of inundation above ground level possible. For east coastal Mass including Cape Cod and Martha's Vineyard, up to one foot of inundation above ground level is possible. - *Confidence and Uncertainty: *High confidence on widespread minor coastal flooding but some uncertainty on areal extent of moderate flooding. The greatest confidence for moderate coastal flooding is at Nantucket. If higher winds and waves occur then more widespread moderate coastal flooding will occur. Conversely if wind and waves trend lower than moderate coastal flooding will not be as widespread. - *Friday Evening & Saturday Morning High Tides:* minor coastal flooding is possible during these high tide cycles along the entire eastern MA coastline. Thus a Coastal Flood Advisory may be needed for these two tide cycles. *COASTAL FLOOD DEFINITIONS ...* Minor Coastal Flooding - Flooding of the most vulnerable shore roads and/or basements due to height of storm tide or wave splash over. - Majority of roads remain passable with only isolated closures due to nuisance flooding or rip rap. - Isolated inundation up to a foot is possible. - There is no significant threat to life and any impact on property is minimal. - This type of event is covered by a Coastal Flood Advisory. Moderate Coastal Flooding - Widespread flooding of vulnerable shore roads and/or basements due to height of storm tide and/or wave action. - Numerous road closures are needed. - Lives may be at risk for people who put themselves in harm’s way. - Isolated damage of very vulnerable structures such as docks or house decks/porches near the high tide line may be observed. - Pockets of inundation up to 3 feet above ground are likely. - This type of event is covered by a Coastal Flood Warning. The link below provides Coastal Flood Threat and Inundation Mapping ... https://www.weather.gov/box/coastal *Strong to Damaging Winds: * - *Locations: *Cape Cod, the Islands and east coastal Mass. - *Timing: *Strongest north to northeast winds occur today between roughly 8 am and 4 pm. - *Winds*: gusts up to 60 mph for Cape Cod, the islands and Cape Ann, and up to 50 mph for east coastal Mass. - *Impacts: *Possible downed trees and power lines. - *Confidence and Uncertainty*: highest confidence for damaging winds is across Cape Cod, the Islands and Cape Ann with wind gusts at or exceeding 60 mph is most likely. A second area of concern is coastal Plymouth county where winds may be just as strong.

[2020-04-02 PM] NWS Boston EM Briefing: Strong/Damaging winds, Minor to Moderate Coastal Flooding for eastern Mass, Cape Cod, & the islands
by BOX Operations - NOAA Service Account 02 Apr '20

02 Apr '20

Good afternoon, We continue to track a strong ocean storm southeast of Cape Cod which will push west tonight before moving further offshore on Friday. This storm will bring strong to damaging winds and increasing rough seas with minor to moderate coastal flooding during Friday morning's high tide. With the expected increase of the wind and seas across eastern areas, all advisories have been upgraded to warnings for tomorrow morning's high tide. Details are below. *Headlines:* - High Wind Warning*: *In effect from early Friday morning through Friday evening for Cape Cod, Nantucket and Martha's Vineyard. - *Wind Advisory*: In effect from early Friday morning through Friday evening for Cape Ann as well as eastern and southern Plymouth county - *Coastal Flood Warning*: In effect for Friday morning's high tide for all of the east coast of MA, including Nantucket and Martha's Vineyard - *Coastal Flood Advisory*: In effect for this evening's high tide for Nantucket Harbor. - Storm Warning: In effect early Friday morning thru Friday evening, for the coastal waters east of Ipswich Bay and Stellwagen Bank National Marine Sanctuary and the offshore waters adjacent Cape Cod and the Islands (excluding Buzzards Bay and Vineyard Sound). - *Gale Warning*: In effect early Friday morning thru Friday evening, for the remaining waters. *Details:* *Coastal Flooding: * *This evening: Minor coastal flooding expected at Nantucket Harbor for this evening's high tide. * *Friday Morning: Widespread Minor with pockets of moderate coastal flooding* - *Locations*: East coastal Mass, Cape Cod and the Islands. - *Timing*: From 6 AM to 10 AM Friday morning. - *Impacts/Inundation*: For Nantucket: One to two feet of inundation above ground level possible. For east coastal Mass including Cape Cod and Martha's Vineyard, up to one foot of inundation above ground level is possible. - *Confidence and Uncertainty: *High confidence on coastal flooding, greatest confidence for minor structural damage for Nantucket. A storm track closer to the southern New England coast may further elevate the coastal flood threat. *Strong to Damaging Winds: * - *Locations: *Cape Cod, the Islands and east coastal Mass. - *Timing: *Northeast winds increase late tonight, with peak gusts Friday morning thru afternoon. - *Winds*: Northeast wind gusts up to 60 mph for Cape Cod and the islands, and up to 50 mph for east coastal Mass. - *Impacts: *Possible downed trees and power lines. - *Confidence and Uncertainty*: Moderate to high confidence on gusts producing minor to moderate impacts across Cape Cod and the Islands. A closer storm track to coastal southern New England would expand the coverage of stronger northeast winds further inland. In that situation, strong winds capable of minor tree/powerline damage could be possible as far west as I-95.
