NYCEM ISSUES ISSUES TRAVEL ADVISORY FOR POTENTIAL HEAVY RAINFALL STARTING MONDAY THROUGH TUESDAY MORNING

Monday is also a Gridlock Alert Day due to an evening World Cup Game at New York New Jersey Stadium

NEW YORK - New York City Emergency Management (NYCEM) has issued a travel advisory for Monday, June 22. The National Weather Service (NWS) forecasts rain developing late Monday morning and becoming moderate to heavy, with thunderstorms possible Monday afternoon and again late Monday night into early Tuesday. Total rainfall is expected to reach 0.75 to 2 inches widespread, with localized amounts up to 4 inches. Rainfall rates of 0.5 to 1 inch per hour are likely, with rates of 1.5 to 2 inches per hour possible during the strongest thunderstorms. Southeasterly winds of 10 to 15 mph will bring gusts up to 30 mph, with isolated gusts of 40 to 50 mph possible during thunderstorms. There is a risk of severe weather from Monday morning through Tuesday morning. Light rain may linger through mid Tuesday morning. Monday is also a Gridlock Alert Day, with the World Cup match between Senegal and Norway scheduled for 8 p.m. at New York New Jersey Stadium.

"As New Yorkers head home from work and fans make their way to NYNJ Stadium, we're expecting a period of heavy rain and thunderstorms across the city. I'm urging everyone to plan ahead and give themselves extra time to travel safely," said Mayor Zohran Mamdani. "If you can, take public transit, leave early, and bring a raincoat or umbrella. Most importantly, no destination is worth risking your safety. If conditions become severe, stay indoors and wait until it's safe to travel."

"Monday's forecast will bring rain and the potential for thunderstorms with gusty winds, impacting commuting times and outdoor activities. We are coordinating with the FIFA Host Committee and New Jersey for any impacts to the fan fests in Brooklyn and Queens, as well as travel to and conditions during the game," said NYCEM Commissioner Christina Farrell. "We encourage everyone to add extra time to their commute, avoid flooded roadways and basements, clear catch basins whenever possible and stay informed with the latest weather updates by signing up for Notify NYC."

On Monday, rain is expected to begin after 10 a.m. and become moderate to heavy through the day. The chance for thunderstorms increases Monday afternoon between 1 and 6 p.m., with a brief lull possible Monday evening before additional thunderstorms become most likely from late Monday night through early Tuesday morning. Lingering drizzle and scattered light rain may continue through mid Tuesday morning. Localized flash flooding is likely in poor-drainage areas during thunderstorm activity, with a low overall flood threat. Ponding on roadways may develop during periods of intense rain and in locations where storm drains are clogged. Potentially damaging wind gusts during thunderstorms could down tree branches and blow away unsecured outdoor objects. A moderate rip current risk is also expected at area beaches on Monday.

During expected heavy rain, NYCEM activates the City's Flash Flood Emergency Plan, coordinating closely with NWS, city and state agencies, utility providers, and private sector partners. The Flash Flood Plan includes pre-storm actions such as targeted inspection and clearing of catch basins in flood-prone areas by the Department of Environmental Protection and the Department of Transportation to help reduce street flooding before heavy rain begins.

The Downed Tree Task Force has been put on alert to respond to any fallen trees or branches, as well as the Tow Truck Task Force to assist with any stranded vehicles. NYCEM is leading interagency calls to ensure partners are briefed on potential impacts and prepared to increase response operations as needed. NYCEM's 24/7 Watch Command continuously monitors weather conditions and tracks developing systems in real time.

In order to prepare for Monday's weather, NYCEM and partners have taken the following actions:

• The Emergency Operations Center at NYCEM will be activated for the FIFA match in NYNJ Stadium, and to monitor weather impacts with representatives from partner agencies.
• Additional staff will be added to NYCEM's Watch Command Unit.
• Weather forecast and preparedness messaging have been going out to the public over the last several days. The public warning messages are reminding New Yorkers to plan ahead, clean catch basins, and avoid flooded streets.
• Our partners at the Department of Sanitation, Department of Transportation and the Department of Environmental Protection are clearing catch basins.
• Agencies are prepared to provide additional personnel as needed.

New Yorkers should allow extra travel time during periods of heavy rain, especially Monday evening. Monday is also a Gridlock Alert Day as soccer fans travel to New Jersey for the match scheduled at 8 p.m. Avoid driving through flooded streets. Even shallow water can stall vehicles. Secure loose outdoor items such as patio furniture or trash bins before winds increase. If thunder is heard, move indoors and stay away from open areas. Clear debris from nearby storm drains if it is safe to do so to help reduce street flooding.

NYCEM recommends the following preparedness actions for New Yorkers in flood-prone regions and low-lying areas:

PREPARING FOR RAIN

• Do not enter flooded basements and leave your basement before it starts to flood.
• 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.
• Subscribe to Notify NYC at NYC.gov/NotifyNYC, download the app in your phone's app store, or dial 311.
• Keep a battery-powered radio ready for timely updates, particularly if power outages are expected.
• If it's safe to do so, 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.
• If you are driving and come to a flooded street, turn around.
• Do not walk or drive into standing water. You never know how deep it is or what is under it.

To prepare 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.
