Can Planes Fly Through Hurricanes?
Sources: NOAA, FAA, NHC, Aviation Week · Updated May 2026
Commercial passenger jets do not fly through hurricanes. Airliners deviate around tropical cyclones, typically by 100–200+ nautical miles, because severe turbulence, lightning, hail, icing, and extreme updrafts inside the storm core exceed normal operating envelopes. Specialized aircraft — NOAA's WP-3D Orion turboprops and Gulfstream IV-SP jet, plus the US Air Force Reserve 53rd Weather Reconnaissance Squadron ("Hurricane Hunters") flying WC-130J Hercules — are designed and crewed to fly into hurricanes to collect data used by the National Hurricane Center for forecasts. Above the storm (typically FL400+), the Gulfstream IV-SP samples steering currents that determine where the hurricane will go next.
Why commercial planes avoid hurricanes
A mature hurricane is a vertically deep convective system extending from sea level to 50,000–60,000 ft. Cruising airliners typically fly at FL350–FL400 (35,000–40,000 ft) — directly inside the upper tops. Inside the storm:
- →Severe turbulence: vertical gusts can exceed 50 ft/s, capable of injuring unbelted passengers and stressing the airframe.
- →Lightning and hail: continuous electrical activity and large hail damage radomes, leading edges, windshields.
- →Icing: supercooled liquid water at altitude overwhelms anti-ice systems.
- →Engine ingestion: heavy precipitation and hail can cause flameouts or compressor damage.
Standard airline practice and FAA guidance is to avoid thunderstorm cells by 20 nautical miles laterally and to give entire convective complexes — including tropical cyclones — a much wider berth. For a hurricane, deviation is typically 100–200+ NM, and large storms can force complete reroutes of dozens of flights at once.
Hurricane categories and operational impact
The Saffir-Simpson scale categorizes hurricanes by sustained surface winds. From an aviation standpoint, the inner core is hazardous at any category; what changes with intensity is the size of the affected area and the likelihood of airport closure at the destination.
| Category | Sustained winds | Aviation impact |
|---|---|---|
| Tropical Storm | 39–73 mph | Local rerouting; ground stops at small coastal airports. |
| Cat 1–2 | 74–110 mph | Affected airports close 6–12 h before landfall; reroutes 100+ NM. |
| Cat 3 (major) | 111–129 mph | Major hub closure (e.g., MIA, MCO, IAH); widespread cancellations. |
| Cat 4–5 | 130+ mph | Multi-day regional shutdown; aircraft repositioned out of region. |
Who flies into hurricanes — and why
NOAA operates two Lockheed WP-3D Orion four-engine turboprops — registration N42RF "Kermit" and N43RF "Miss Piggy" — and a Gulfstream IV-SP (G-IV). The WP-3Ds fly directly through the eyewall at altitudes of 5,000–10,000 ft, measuring wind, pressure, temperature, and humidity. The Gulfstream operates at up to 45,000 ft around the storm's upper periphery, releasing dropsondes into the steering flow.
NOAA has contracted Lockheed Martin to build two new WC-130J Hercules aircraft to eventually replace the aging WP-3D fleet, with delivery expected around 2030.
Based at Keesler AFB in Biloxi, Mississippi, the 53rd WRS operates ten WC-130J Hercules aircraft. They fly fixed-altitude (typically 10,000 ft) patterns through Atlantic and Pacific tropical cyclones, providing data the National Hurricane Center uses to improve track and intensity forecasts.
Satellite imagery shows storm structure from above but cannot directly measure surface winds, central pressure, or the 3D wind field. Reconnaissance dropsondes and onboard sensors close that gap. Studies have shown that assimilating Hurricane Hunter data into numerical weather models reduces track-forecast error by 15–30%.
How airlines handle hurricane season
Airlines monitor NHC advisories from the moment a tropical depression forms. The general response sequence:
- →96–72 h before landfall: dispatch and meteorology teams plan reroutes for transit flights. Aircraft scheduled to be on the ground at threatened airports are repositioned.
- →48–24 h: airlines issue travel waivers allowing passengers to rebook without fees. Inbound capacity is reduced.
- →12–6 h: affected airports typically close; remaining flights cancelled.
- →Post-landfall: airports reopen once ATC, runways, and ground infrastructure are verified. Backlog clears over 2–4 days.

What about flying around a hurricane?
Even when an airport remains operational, transit flights are rerouted well clear of the storm system. Reasons:
- →Cirrus outflow extends 200–400 NM from the center and can hide embedded convective cells.
- →Surface low-level jets create wind-shear hazards near coastal arrival corridors.
- →Flow control imposed by FAA Air Traffic Control System Command Center limits sector throughput during major events.
For passengers, this means adjacent unaffected airports (Atlanta, Dallas, Charlotte) often absorb diverted traffic during a major Gulf or Atlantic landfall, and connection times tighten across the network for several days.
Has a commercial airliner ever flown through one accidentally?
Inadvertent penetrations have occurred — usually when forecast tracks shifted faster than flight planning. The most common outcome is a rough ride and unscheduled diversion to an alternate. Modern weather radar, real-time data uplinks, and tighter dispatch monitoring have reduced these events significantly, but they still occur a handful of times per season globally.
