Phase 1: Airport Arrivals and Flight Advisory
Travelers arriving at major East Coast airports should prepare for flight delays and potential scheduling changes due to low visibility from drifting wildfire smoke. If you are landing at JFK, Newark, or Boston Logan, check your flight status via your airline’s portal before leaving for the airport. Ground delays are active in multiple states.
Ensure you have activated your mobile data upon landing. Getting connected immediately will help you stay updated with notifications from air traffic control and weather agencies.
Phase 2: Transiting Safely Through City Commutes
In addition to air quality issues in the East, intense summer storms have triggered localized flooding in the South, particularly in Texas. Avoid transiting through underpasses or driving along low-water crossings. If you encounter flooded roads, turn around immediately.
When booking rideshare services in storm-affected areas, confirm with your driver that they are using updated navigation routes that bypass blocked avenues.
Phase 3: Postponing Regional Excursions and Road Warnings
National parks and scenic highway drives in several states have faced alerts for fire, smoke, or water damage. The National Weather Service has urged the public to stay informed on regional warnings. Consider postponing regional camping or hiking activities until weather warnings clear.
Check the latest alerts on the National Weather Service portal before embarking on any intercity road trips.
Phase 4: Savoring Local Food and Dining Tipping While Sheltering
If you are sheltering in your hotel or rental home to avoid poor air quality or rain, ordering food delivery is a safe option. Delivery drivers in storm or haze-affected areas face additional safety hazards. In the US, it is standard practice to tip delivery couriers 15% to 20% for their services, especially during severe weather conditions.
Mobile and contactless credit card payments are widely accepted on all US delivery platforms, allowing you to manage transactions easily.
