Flight planning: Morristown Municipal MMU / KMMU

What a pilot looks at before a flight from or to Morristown Municipal in Morristown, New Jersey, in plain English. The warnings, reports and winds below come from the government's aviation weather service and the restrictions from the FAA, refreshed every few minutes. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools.

Warnings in force SIGMETs and AIRMETs whose area covers this field

SIGMET 2E: thunderstorms (a convective SIGMET) up to 31,000 ft, moving from the southwest at 20 knots, until 10:55 pm EDT (02:55 UTC).

VALID UNTIL 0255Z
CT NY NJ PA DE MD AND NJ NY CT CSTL WTRS
FROM 30NE SAX-30SSW HTO-30ESE EMI-50WSW HAR-30NE SAX
AREA EMBD TS MOV FROM 22020KT. TOPS TO FL310.

AIRMET SIERRA 3E: low cloud or poor visibility (IFR conditions) (due to ceilings below 1,000 ft, visibility below 3 miles, precipitation, mist).
AIRMET TANGO 2W: low-level wind shear (due to air speed loss or gain of 20 knots or more below 2,000 ft above the ground).
AIRMET TANGO 2W: moderate turbulence below 18,000 ft up to 18,000 ft.

A SIGMET warns of weather hazardous to all aircraft (thunderstorms, severe turbulence or icing, volcanic ash); an AIRMET of weather that matters to small aircraft and to flying without instruments (moderate turbulence or icing, low cloud, strong surface wind, mountains hidden in cloud). An area is counted when it covers this field's position.

What pilots in the air told air traffic control or Flight Service: turbulence, icing, cloud tops and bases, temperature, wind, and whatever they remarked on (wind shear on final, a smooth ride). An urgent report is one of severe turbulence or icing, wind shear, or similar. Open "as filed, and in English" for the coded report and its translation line by line.

Winds and temperatures aloft forecast point JFK, 30 nm east of the field · for use 20:00–03:00 UTC

Height	Wind from	Speed	Temperature
3,000 ft	140° (southeast)	43 knots
6,000 ft	170° (south)	35 knots	13 °C
9,000 ft	230° (southwest)	18 knots	9 °C

Based on data from the 11th at 18:00 UTC; valid on the 12th at 00:00 UTC for use 20:00 to 03:00 UTC; temperatures above 24,000 ft are below zero. Heights are above sea level; the lowest rows are left out where the ground is already that high.

Temporary flight restrictions within 50 nautical miles, from the FAA's list

5/2811 NEW YORK, NY, Monday, October 20, 2025 through Tuesday, October 20, 2026 Local 19 nm east · security · until 20 October · ZNY

Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (a closed runway, lights out, a crane) are not shown here: the FAA's notice search is not open to sites like this one at this time, and the application for the FAA's data feed is in hand.
