Pattern
What Plymouth County gets alerted for
Every alert that named Plymouth County in the last 12 months, by type. Records begin August 30, 2026, so this fills in over the year.
Plain English
What these alerts mean
A warning means the hazard is happening or about to; a watch means conditions favour it; an advisory is a lesser hazard still worth planning around.
Frost is expected on the ground. Cover sensitive plants overnight.
Flooding of rivers, streams or low-lying areas is occurring or expected. Avoid flooded roads and monitor river levels.
Minor coastal flooding is expected, usually around high tide. Expect water on low-lying roads near the shore.
Conditions are favourable for flooding. Have a plan in case a warning is issued.
Large breaking waves are expected on beaches, with dangerous rip currents. Stay off jetties and out of the water.
Significant coastal flooding is occurring or imminent, typically at high tide. Move away from low-lying shoreline areas.
Sustained winds of 30 mph or more, or gusts to 45 mph, are expected. Use caution driving high-profile vehicles.
Sustained winds of 40 mph or more, or gusts of 58 mph or more, are expected. Secure loose objects and expect downed trees and power lines.
Flash flooding is occurring or imminent. Move to higher ground; never drive into water covering a road.
Rip currents that can pull swimmers offshore are expected. Swim near a lifeguard and know how to escape a rip.
Significant coastal flooding is possible. Prepare to protect property near the shore.
Damaging winds are possible. Secure loose objects ahead of time.

Questions
About Brockton alerts
How do I get Brockton weather alerts on my iPhone?
Install Forecast Bar, add Brockton as a location, and turn on severe weather alerts. Every NWS warning, watch and advisory for Plymouth County then arrives as a push notification at the moment of issue, with Critical Alerts available for the most dangerous warnings. Forecast Bar also runs on iPad, Apple Watch, Mac and Apple TV.
Where do these alerts come from?
From the National Weather Service alert feed (api.weather.gov). NWS issues alerts by county and by forecast zone; this page lists every product that names Plymouth County, the county Brockton sits in. Forecast Bar checks the feed continuously and this page refreshes within a few minutes of a change.
What is the difference between a watch, a warning and an advisory?
A warning means the hazard is occurring, imminent or very likely: act now. A watch means conditions are favourable for it to develop: prepare and stay informed. An advisory covers a hazard that is less serious than a warning but can still cause real inconvenience or danger if you are not ready for it.
Can I get this data as JSON?
Yes. /weather-alerts/ma/brockton.json returns the active alerts, the last 30 days and the 12-month counts for Brockton, refreshed every minute. Please cache responses and credit National Weather Service as the source.
