If a SIGWX chart shows a change in wind speed of 50kts, which symbol would you expect to see?

Explanation:
Wind speed on SIGWX charts is shown with wind barbs, where the symbols encode the amount of wind. A pennant—the small triangular flag on the barb—represents 50 knots. So when the chart indicates a 50-knot change, you would see a pennant on the wind barb at that location. Smaller increments are shown by the other barb elements (long and short barbs), but they do not indicate 50 knots. Arrows or dashes aren’t used to denote a 50-knot change on these charts.
