WARM FRONT SYMBOL

WARM FRONT

OLD

Short, usually intense storms - (thunderstorms,

squalls, tornadoes)

They usually pass fairly quickly.

Bring a steady drizzle, light

rain; a low cloud base, and

possibly fog.

They may take a day or two to

pass.

COLD FRONT SYMBOL

COLD FRONT

Stationary Front

The differences in their temperatures and pressures have almost equalized.

Result - usually little wind but a long period of rain

Stationary Front

OCCLUDED FRONT SYMBOL

OCCLUDED FRONT

The cold front contributes high winds and unsettled conditions; the warm front contributes steady heavy rain

OCCLUDED FRONT
