Contour lines (isobars) are drawn at intervals of 2 hPa (hectopascals). The isobar value is divisible by 2 (e.g., 1020, 1018, 1016, etc.). Areas of expected rainfall within the forecast period are shaded. Arrows indicate wind direction, with strength proportional to the arrow's size and feathering.
