8

Weather watch

A watch is used when the risk of hazardous weather or hydrologic event has increased significantly, But its occurred, location, and/Or timing is still uncertain.

9

Weather warning

A warning is issued with a hazardous weather or hydrologic event is occurring, is imminent, or has a very high probability of occurring. A warning is used for conditions posing a threat to life or property.

10

Foen: as per IRPG

40 to 60 mph: up to 90 mph at 20 feet

11

Beaufort scale

Use to estimate 20 ft windspeed

12

Haines Index

Used to indicate the potential for rapid fire growth do to dry and unstable atmospheric conditions over A fire area.. It is a simple way to measure the atmospheres contribution to the fire's growth potential.

2: very low Potential ( moist and stable lower
atmosherer)
3: very low potential
4: Low Potential
5: Moderate Potential
6: High Potential

13

Burning Index

Reflect the change in fine fuel moisture content and wind speed and is highly valuable day to day.
Fire danger can be loosely associated with flame lengt by dividing the BI by 10. The BI is readilly affected by wind speen and fine fuel moisture.
