The New York City Emergency Management Department (NYCEM) today placed New York City communities under a Travel Advisory to elevate their readiness levels in anticipation of coastal flooding Saturday, March 9, to Sunday, March 10. The agency recommends New Yorkers—particularly those residing or operating businesses in coastal areas—remain alert and take preparedness actions.
Strong offshore winds in combination with a new moon will result in higher than normal water levels near and along the coast during several high tide cycles from tomorrow morning to Sunday morning, the worst of which is expected Saturday evening and Sunday morning. Additionally, as a storm moves through the region tomorrow, periods of moderate to briefly heavy rain Saturday evening may exacerbate flooding along the shore. Significant inland flooding due to heavy rainfall is not expected, although minor rainfall flooding will be possible in low-lying and poor drainage areas.
The National Weather Service has issued several citywide flood alerts for potential flooding. In southern Queens, a Coastal Flood Watch is in effect from 6:00 p.m. Saturday to 1:00 p.m. Sunday to account for flooding during two high tide cycles on Saturday evening and again Sunday morning. The Bronx and northern Queens are also under a Coastal Flood Watch valid from 9:00 p.m. Saturday to 1:00 a.m. Sunday for flooding during one tide cycle. In these areas, 1 to 2 feet of water, with up to 3 feet in a worst case scenario, is expected to result in widespread flooding of areas near the shore, including roads, parking lots, parks, and homes and businesses with basements near the waterfront. Numerous road closures are likely, and vehicles parked in vulnerable areas near the waterfront will likely become flooded.
Coastal Flood Statements are also in effect for Brooklyn, Manhattan, southern Queens, and Staten Island for minor flooding tomorrow morning with up to 1 foot of flooding possible along vulnerable shorelines. High tides in these areas will peak around 7:00 a.m. tomorrow.
Areas currently under a Watch may be upgraded to Coastal Flood Warnings tomorrow, while additional Coastal Flood Advisories or Statements will be possible for all other city shorelines tomorrow evening and again Sunday morning.
A prolonged period of gusty winds is also expected this weekend into early next week. Winds will ramp up tomorrow evening to gusts of 30 to 40 MPH with peak gusts of 45 mph possible along the coast. Gusts of 30 to 40 MPH will continue throughout the day Sunday into Monday morning and may further increase on Monday afternoon, with peak gusts up to 50 MPH possible into the evening. Periods of strong winds may result in loose items being blown around, hazardous driving for high profile vehicles, downed trees and tree limbs, and potential power outages.
NYCEM is collaborating with the National Weather Service and monitoring the latest forecasts, particularly the potential for coastal flooding. To ensure real-time awareness and a coordinated response, NYCEM is organizing specialized interagency briefings to keep essential stakeholders well-informed of emerging risks, fine-tune operational strategies specific to coastal flooding, and reinforcing its readiness for scaled-up emergency responses should conditions warrant. Critical assets and specialized units are on standby prepared for activation as conditions necessitate. Roads, parking lots, and properties in low-lying areas near the shoreline could potentially experience minor flooding.
NYCEM recommends the following preparedness actions for New Yorkers for those in coastal flood-prone regions and low-lying areas:
- Communication and Information: Before and during an emergency, the City will send emergency alerts through various channels, including Notify NYC, available in 13 different languages, with a special sub-group dedicated to Basement Apartment Dwellers. Register at NYC.gov/NotifyNYC or dial 311. Keep a battery-powered radio ready for timely updates, particularly if power outages are expected.
- Gather Supplies: Every household member should have a Go Bag packed with essential items, such as bottled water, non-perishable food, and basic medical supplies.
- Tidal Awareness and Coastal Barriers: Monitor tide tables and storm surge forecasts. Know when high tides are expected in your vicinity and be prepared to adjust your plans. Where feasible, deploy sandbags or other deployables suitable for a residence to reduce the risk of tidal water intrusion.
- Watercraft and Boat Security: If you own boats or watercraft, secure or relocate them immediately. Fluctuating tides can not only carry them away but loose watercraft can cause additional damage.
- Storm Drains and Local Warnings: Regularly check and clear any nearby storm drains to help manage water runoff and lessen the chances of localized flooding. Pay attention to localized warnings, especially those pertaining to rip currents and high waves.
- Beach Closures and Coastal Roads: Remain updated on any beach closures, as flooding can swiftly make these areas hazardous. Beaches are closed to swimming. Plan alternative travel routes to avoid low-lying coastal roads that may be susceptible to flooding.
- Home Safety and Utility Measures: Ensure your home's sump pumps are operational and familiarize yourself with how to safely shut off utilities like gas, water, and electricity. If you reside in a basement or below-grade apartment, be particularly vigilant, as these areas are more susceptible to flooding. Follow City guidance for additional actions specific to below-grade dwellings. Subscribe to Notify NYC’s Basement Apartment Dweller subgroup for key alerts.
- Document & Insurance Review: Secure essential documents in waterproof containers and maintain digital backups. Review your insurance to ensure you have specialized flood coverage, as standard policies often don't cover flood and wind damage. Consider enrolling in the National Flood Insurance Program. Learn more at www.floodsmart.gov.
- Prepare for Outages: To gear up for potential power disruptions, keep your cell phones charged, stock up on supplies. If power outages are predicted, consider adjusting your refrigerator and freezer to colder settings to extend the shelf life of perishable items. Ensure that flashlights and battery-operated radios or TVs are functional, keeping extra batteries on hand. If you rely on Life Sustaining Equipment (LSE) and lose power, dial 911 for immediate assistance, and remember never to use generators indoors. Check on vulnerable individuals in your community, such as older adults and people with disabilities or health conditions, and assist them in their preparations.
- Pet Safety: Make provisions for your pets' safety, including the need to leave your home and to take your pet with you.
- Plan for Special Needs & Check on Your Neighbors: Make it a point to check on neighbors who are older adults or who may require special assistance. If you have a disability or specific access and functional needs, make sure your emergency plan accounts for how these factors could impact your ability to respond quickly and communicate effectively during a crisis. Seek assistance from your family or service providers as needed.
- Avoidance and Caution: Do not venture into flooded areas. These zones may be contaminated or electrically charged. Take preemptive action by assembling a Go Bag with essentials like food, water, and first-aid supplies.
- Documentation: When it's safe, contribute to our collective flood risk understanding by capturing and submitting photos via the MyCoast portal (https://mycoast.org/ny) or the MyCoast app. Don't forget to also file flood reports through 311.
- Real-Time Awareness: Stay updated on changing flood conditions by monitoring real-time flood depth via the FloodNet website (https://www.floodnet.nyc/).
