Phase 1: Airport Arrivals and Flight Advisory
Travelers arriving in the Northeast US should brace for delays. Severe thunderstorms combined with thick haze from Canadian forest fires have caused reduced runway visibility. If you are transiting through JFK, Newark (EWR), or LaGuardia (LGA), expect ground stop programs. Stay updated via your airline’s mobile notifications.
Upon landing, verify your mobile data connection immediately. Reliable data access is essential to receive emergency safety alerts and coordinate alternative transportation options.
Phase 2: Transiting Safely Through City Commutes
Torrents of rain can rapidly flood municipal subway stations and highway underpasses. In New York City, select subway lines have faced service suspensions. Refrain from entering flooded stations. If you are taking taxis or rideshares, ensure the driver is aware of low-water road advisories.
Avoid walking or commuting through stagnant water, as hidden electrical hazards or open storm drains can present serious safety risks.
Phase 3: Postponing Regional Excursions and Road Warnings
Outdoor activities, including hiking in upstate parks, should be suspended due to high flash flood risks and poor air quality. The National Weather Service has issued warnings advising residents and visitors to limit travel. Keep headlights active if driving through regional haze.
Check the national meteorological status portal before embarking on any intercity road trips in the Mid-Atlantic states.
Phase 4: Savoring Local Food and Dining Tipping While Sheltering
Remaining indoors at your hotel or apartment is the safest course of action. If ordering food delivery during severe weather, please be considerate of the delivery riders. In the United States, a tipping rate of 18% to 22% is standard for couriers working during severe weather events.
Card and digital wallet payments are accepted by all major food delivery applications, making it easy to purchase meals without needing to go outside for cash.
