Flight turbulence forecasts and weather guides by route

A transcontinental route that can cross the Southwest, Rocky Mountain region, Great Plains, and several fast-changing weather systems. The exact track varies with winds and air traffic.

The westbound transcontinental track may be adjusted to manage winds, storms, and air traffic. Conditions can differ from the same route flown eastbound.

A central-to-western U.S. route that may cross Plains weather, higher terrain, and dry mountain regions before reaching Southern California.

A route along the eastern United States where tropical moisture, coastal storms, and frontal systems can influence climb, cruise, and arrival.

A southern transcontinental route that can encounter southeastern convection, Plains weather, and western terrain before the Los Angeles arrival.

A northern transcontinental route that may cross the Cascades, Rockies, northern Plains, Great Lakes region, and northeastern weather systems.

A coast-to-coast route that can move from California coastal weather across western terrain, the Plains, and several eastern weather zones. The operating track can shift north or south with winds and thunderstorms.

A route beginning near the Rocky Mountains before crossing the Plains, Midwest, and Northeast. Terrain-driven airflow can matter early, while thunderstorms and fronts may become more important farther east.

A south-central to western route crossing dry plains, desert regions, and areas of higher terrain. Thunderstorms near Texas and mountain or desert airflow farther west can influence different parts of the trip.

Most of the flight is an oceanic cruise, followed by an arrival into Hawaii where trade winds and island terrain can affect the final portion of the trip.

An oceanic route that begins near California coastal weather and finishes in Hawaii's trade-wind environment. Conditions near the airports may feel different from the long cruise over the Pacific.

A route from Southern California across northern Mexico or the southern United States toward the Gulf of Mexico and the Yucatan Peninsula. Desert heating, Gulf moisture, and tropical weather can influence different sections.

An oceanic route leaving the Pacific Northwest and approaching Hawaii from the north or northeast. Pacific storm systems, upper-level winds, and Hawaiian trade winds can affect different stages.

A coastal and oceanic route from the Northeast toward the Caribbean. Frontal weather near New York, Atlantic wind patterns, tropical moisture, and island trade winds can each affect a different phase.

A North Atlantic crossing where the planned oceanic track changes with the jet stream, traffic, and weather. Eastbound and westbound flights may follow different corridors.

A long route that combines a transcontinental crossing with the North Atlantic. The flight can encounter western terrain, central U.S. weather, and a changing oceanic track before reaching the United Kingdom.

A North Atlantic crossing where the route is selected around upper-level winds, organized weather, and oceanic traffic. Conditions near New York and Paris can differ from the cruise environment.

A relatively direct North Atlantic route, but the exact oceanic track still changes with wind, weather, and traffic. Coastal weather at both ends can be more noticeable than long portions of cruise.

A route that combines Midwest weather, an eastern Canada or northeastern U.S. crossing, and the North Atlantic. Conditions can change several times during the long flight.

A long trans-Pacific trip that commonly follows a curved great-circle route rather than a straight line on a flat world map. Track, altitude, and wind conditions can change during the flight.

This trans-Pacific route may arc northward on a globe. Coastal winds near San Francisco, the North Pacific jet, and weather near Japan can influence different phases.

A long trans-Pacific route that usually appears curved on a globe and may shift substantially with the Pacific jet stream. Weather near coastal California, across the ocean, and near Japan should be considered separately.
