Step-by-step explanation:
A weather briefing that is provided wherein the information requested is six or more hours in advance of the proposed departure time is an outlook. Space weather predictions, including outlooks, are a part of what the Space Weather Prediction Center offers online to both scientists and the general public.
These outlooks are important for providing early forecasts about space weather conditions, helping to prepare for any space weather events that can affect Earth's atmosphere and the technology we depend on, such as satellites and communications systems. These outlooks are given a week ahead, enabling adequate preparation time.
