  but probabilities of a wetter season than last year and of 10-year extremes are presented. A wetter season than 2018 is favoured in most boxes east of 30E and between 10N and 10S. Elsewhere a drier season than 2018 is likely in most grid boxes. Probabilities of a season drier than any in the past 10 years (2009

• Understanding convergence zones and the Intertropical Convergence Zone

  . If the winds continue to converge, wet conditions can persist, sometimes resulting in significant rainfall totals and even flooding. Convergence lines are not limited to a particular season and can occur at any time of year. During the summer months, local sea breezes can help form convergence lines
