Which of the following is NOT one of the four activities the AWW checks before issuing WW?

The main idea here is to understand what drives a Weather Watch (WW) for aviation: it’s about convective hazards that can affect flight operations. The AWW checks for factors that indicate active or potential convective storms. Those factors include hazardous convective activity, which signals the presence or imminent development of strong thunderstorms; winds over 50 knots, which bring strong gusts and turbulent conditions tied to convective systems; and funneling tornadoes, which points to tornado potential associated with severe thunderstorms. Severe icing on radar isn’t part of these checks because radar doesn’t directly measure icing conditions; icing is managed by separate aviation weather products (like icing advisories), not by the convective-threat criteria used to decide on a WW. So the item about severe icing on radar doesn’t fit the four checks, which is why it’s not included in the WW issuance process.
