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

02 Apr '20

Good morning. Good afternoon everyone, A strong ocean storm will shift north well southeast of Cape Cod today, then will push west tonight before looping offshore on Friday. This storm will bring strong to damaging winds, increasing rough seas along with minor to moderate coastal flooding during Friday morning's high tide. With the expected increase of the wind and seas across eastern areas, headlines have been upgraded to warnings and advisories. 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 Nantucket Harbor. - *Coastal Flood Advisory*: In effect for this morning's high tide for Nantucket Harbor. - *Coastal Flood Advisory*: In effect for Friday morning's high tide for east coastal Mass (*including the city of Boston*), Cape Cod 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: * *This Morning: Minor Coastal Flooding* - *Locations*: Nantucket Sound - *Timing*: From 6 AM to 10 AM. - *Impacts/Inundation*: Up to one foot of inundation above ground level in low-lying areas near shorelines. *Friday Morning: Minor to 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 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 and the Islands and east coastal Mass. - *Timing: *Northeast winds increase late tonight, with peak gusts Friday morning thru afternoon. - *Winds*: North 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. The attached graphics include current headlines in effect, the maximum wind gust and maximum wave height. Thank You!

[2020-03-23 PM] NWS Boston EM Briefing for Snow Event Tonight
by BOX Operations - NOAA Service Account 23 Mar '20

23 Mar '20

Good afternoon, Here is the latest on the snow event impacting Connecticut, Rhode Island and Massachusetts. The key takeaway is snow amounts have been increased from previous forecast across northern CT into northwest RI and northeast MA. Please see the attached graphics which include: - NWS Winter Storm Warnings & Winter Weather Advisories - NWS Official Snowfall Forecast *NEW: * - Winter Weather Advisory for all of northern CT including Hartford, Windham and Tolland counties *What's Changed*: - Increased snow amounts across northern CT from Hartford to the RI border to 2-4 inches of snow before mixing with sleet and then changing over the rain 5 pm to 8 pm - Increased snow amounts across the northern portions of Middlesex and Essex counties where the Winter Weather Advisory has been posted. 2-4" expected here with highest totals likely along and near the NH border *What/Where/When: * - Western and central MA snow heavy at times continue into this evening then tapering off between 11 pm and 2 am. Snow will accumulate 4-8 inches across the high elevations with 2-4 inches in the valleys.* Locations that receive over 4 inches there is an increased risk of tree damage and isolated power outages given the heavy wet snow.* - Snow across RI and eastern MA (along and northwest of Boston to Providence) changes over to sleet and then rain between 5 pm and 8 pm with snow accumulations ranging from a coating up to 2 inches north and west of Boston to Providence. Snow accumulates mainly on the colder non paved surfaces with main roads remaining just wet - Little if any snow southeast of Boston to Providence line *Uncertainty:* - The exact timing of the changeover and resulting duration of snow is somewhat uncertain. If the changeover is delayed by an hour or two snow totals will be slightly higher. Conversely if the changeover occurs quicker than forecast snow totals will be lower. For more details, check out our winter page: https://www.weather.gov/box/winter This will be the last email briefing unless conditions change.

[2020-03-23 AM] NWS Boston EM Briefing for Coastal Storm Monday into Tuesday Morning
by BOX Operations - NOAA Service Account 23 Mar '20

23 Mar '20

Good morning everyone, Here is the latest thinking about the coastal storm which will pass southeast of New England today into early Tuesday. It will bring snow to much of the area this afternoon before a change to rain Monday night. This is expected to be a minor snowfall event, with the exception of the higher elevations of western and central MA, where as much as 8 inches of snow is possible. *NEW:* - Northwest Middlesex County changed from a Winter Weather Advisory to a Winter Storm Warning *What/Where/When:* - Snow develops from west to east across much of southern New England Monday afternoon, except near the South Coast, Cape Cod, and the Islands where mainly rain is expected. - Snow is expected to be heavy at times late Monday afternoon into evening, especially in the Berkshires and northern Worcester Hills. Heavy snowfall rates could lead to snow-packed roads and difficult travel. - Snow mixes with and changes over to rain from south to north. The higher elevations of northern Worcester County and the Berkshires are expected to remain mostly snow. - The consistency of the snow will be heavy and wet. *Uncertainty:* - Snow amounts will be highly elevation-dependent, leading to potentially significant countywide differences in snow totals. - Portions of northwest Hartford County may see 3-5" with quickly diminishing amounts to the south and east. - If the coastal storm passes farther offshore, snowfall totals will be less, especially across the interior. - Conversely, if the storm tracks closer to southern New England, there would be less snow across most of the region, since the higher accumulations would shift to the northwest of MA.
