For too long, not every neighborhood has had equal access to tree canopy. That changes today. NYC’s first-ever #UrbanForestPlan lays out a path to a cooler, healthier, more equitable city, with a goal of 30% canopy by 2040. Read the plan: nyc.gov/assets/climate…

NYC: We've got a little more rain headed our way today before the weather starts to dry up. Stay safe and stay prepared.

Se anima a los neoyorquinos a prepararse para lluvias fuertes que se esperan en NYC. Durante las lluvias fuertes, vaya a zonas más altas. Si está en un sótano, suba a un piso más alto. Si debe viajar, tenga cuidado. Info: on.nyc.gov/2WYDNJS.

Intermittent heavy rain possible in NYC 5/24 - 5/25. Do not enter flooded roadways or buildings. Stay OUT of flooded basements. Call 311 to report clogged catch basins or flooding. Before traveling, visit mta.info or 511ny.org for travel impacts.

We had a rainy day, and we’ll have a rainy night. The heaviest rainfall is expected to begin in the early hours of the morning and continue through midday tomorrow.  While flash flooding is not forecasted, conditions can change quickly — especially overnight — and it’s never too soon to learn how to stay safe during a storm. Here’s what you can do right now: ➡️ Text NOTIFYNYC to 692-692 for emergency alerts. ➡️ Use caution when traveling and take mass transit if possible. ➡️ Visit nyc.gov/beready to learn more and make a plan for you and your family. If flooding occurs: ➡️ Call 911 if you are in immediate danger, trapped by rising water, or see a life-threatening emergency. ➡️ Floodwater can rise rapidly, conceal hazards, and carry electrical current or contamination. ➡️ Avoid flooded basements, subway stations, and underpasses. ➡️ Never walk, swim, or drive through floodwater. ➡️ If you live in a basement apartment, move to higher ground immediately. ➡️ File a @NYC311 service request for issues that require a City response: basement flooding, sewer backups, downed trees, mold, or power outages. ➡️ Report damage at reportdamage.nyc.gov to help the City assess impacts and secure federal recovery resources. Rain or shine, we get through weather together. Stay vigilant, make a plan, and look out for one another.

New Yorkers shouldn’t have to worry every time it rains. Ahead of this weekend’s storms, City workers have been out across all five boroughs clearing and inspecting catch basins in flood-prone neighborhoods. Today I joined @NYCWater in Bushwick to clear a catch basin overflowing with debris and litter on Knickerbocker Avenue, one of the areas hit hardest by Wednesday’s storm. If you see a clogged catch basin, call 311. And if you’re able, help your neighbors by clearing leaves or litter from nearby grates before the rain arrives.

NYCEM reminds New Yorkers to prepare for heavy rain 5/23 - 5/24. Basement flooding can happen quickly and be life-threatening. Move to higher ground if needed and STAY OUT of flooded basements. Limit travel and do not enter flooded roads. More info: nyc.gov/beready

This weekend will be a rainy one, and whenever and wherever it rains, conditions can worsen quickly. New Yorkers should always be prepared to stay safe: Text NOTIFYNYC to 692-692 for emergency alerts. If you must travel, use caution and use mass transit if possible. Never walk, swim, or drive through floodwater. If you live in a basement, move to higher ground if flooding occurs. Call 911 if you are in immediate danger, trapped by rising water, or see a life-threatening situation. Visit nyc.gov/beready for more safety guidance.

Notify NYC Basement Alerts are designed to warn those living in basement apartments about life-threatening weather conditions. For a limited time, New Yorkers can skip the usual sign-up process for receiving Basement Alerts by filling out this simple form: on.nyc.gov/Basements

NYers are encouraged to prepare for potential heavy rain impacting NYC from Sat, 5/23 to Sun, 5/24. During periods of heavy rain causing flooding, move to higher ground. If in a basement, move to a higher floor. If you must travel, use caution. More info: nyc.gov/beready

Weather Alert: @nycemergencymgt is monitoring forecasts & asking NYers to plan for potential heavy rain starting 5/23. Never travel over flooded roadways & be prepared to move to higher ground if needed. Info: weather.gov/okx & nyc.gov/BeReady.

In the hours and days after flash flooding, NYCEM offers the following tips from nyc.gov/beready Stay out of flooded basements. Standing water near electrical equipment is life-threatening. Do not walk or drive through standing water. Even after rain stops, flooded streets can remain dangerous and may conceal hazards. After excessive rainfall events, streets and underpasses may stay flooded for hours. Wash thoroughly if you touched floodwater. Floodwater can carry sewage, bacteria, and other contaminants. Wash your hands and any exposed skin with soap and water. Clean affected surfaces with a bleach solution. When cleaning up after a flood, disinfect surfaces with a diluted bleach solution under proper ventilation. Never mix bleach and ammonia — the combination creates dangerous fumes. Throw away food that touched floodwater. Do not eat or use any food, including canned goods, that came into contact with floodwater. Watch for mold. Mold can begin growing within 24–48 hours after flooding — and excessive rainfall that causes slow seepage into walls or floors can create mold conditions even without visible standing water. If your home has mold or you need cleanup help, contact 311. Pump out flooded basements slowly. Remove about one-third of the water per day — not all at once. Water-saturated soil outside your walls creates pressure, and removing water too quickly can cause walls to crack or collapse. This is especially important after prolonged rainfall, when surrounding soil may be heavily saturated. Document damage before cleaning up. Take photos and videos of all damage before removing water or debris. This will help with insurance claims and disaster assistance applications. Check on your neighbors. After a flood, check on elderly neighbors, people with disabilities, and anyone in basement apartments or low-lying units who may need extra help.

NYC's sewer system was built to handle 1.75"/hour but yesterday's storm brought the equivalent of 6"/hour in some areas. Our crews worked overnight to respond and are continuing today. Report clogged catch basins here: on.nyc.gov/2XM4jEU

NYC Parks forestry crews are out in full force this morning to clean up debris from the storm. We have all hands on deck working to ensure that NYC's streets and parks are safe and clear.

Be Ready for Thunderstorms Call 911 if you are in immediate danger or see a life-threatening situation. If you hear thunder, go inside. Get into a sturdy building and stay there. Move away from windows. Go to an interior room on a lower floor. Stay away from glass doors, porches, balconies, and rooftops. Do not touch electrical equipment or plumbing(sinks, showers, or baths) during a thunderstorm. Avoid corded phones. If a Severe Thunderstorm Watch or Warning, or High Wind Watch or Warning is issued, go to your safe indoor spot and stay there until the warning expires. If you are in a mobile home or temporary structure, leave immediately and go to the nearest sturdy building. These structures are not safe in severe conditions, even if they are secured. If you cannot get indoors, stay away from trees, power lines, scaffolding, open fields, and bodies of water.
