🌫️ Temperature & Dew Point Awareness

One of the biggest risks in early spring flying is the unpredictability of fog and low visibility. As temperatures fluctuate throughout the day, the dew point spread can shrink rapidly, leading to unexpected fog formation.

🌡️ Watch for early morning fog, especially in valleys and low-lying areas.
🌡️ Be aware of rapid visibility changes during sunrise and sunset due to temperature shifts.
🌡️ Consider delaying departures until conditions improve, especially in marginal VFR conditions.

---

⛈️ Navigating Rain & Thunderstorms

March marks the beginning of thunderstorm season, and rapidly developing convective activity can catch unprepared pilots off guard. While thunderstorms are more common in late spring, March can still produce isolated strong storms, particularly along advancing cold fronts.

⚡ Check convective SIGMETs and be aware of rapidly forming cells along your route.
⚡ Avoid flying through towering cumulus clouds, as they can quickly develop into thunderstorms.
⚡ Plan alternate routes in case the weather deteriorates mid-flight.

🦅 Wildlife Hazards – Bird Strikes & Migration

Springtime also signals the return of migratory birds, which increases the risk of bird strikes—particularly near lakes, rivers, and wooded areas.

🦉 Be extra vigilant during takeoff and landing, as birds are more active at lower altitudes.
🦉 Report any bird strikes to the FAA and local aviation authorities.
🦉 Use landing lights during climb and descent to increase visibility and reduce bird strike risks.
