More late sum­mer rain pre­dicted for Zu­l­u­land re­gion

Eyethu Baywatch - - NEWS • IZINDABA - Tam­lyn Jolly

ABOVE av­er­age late-sum­mer rain­fall ac­com­pa­nied by lower-than-nor­mal tem­per­a­tures are what Zu­l­u­lan­ders can look for­ward to in the com­ing months.

This ac­cord­ing to the South African Weather Ser­vice (SAWS) whose Sea­sonal Cli­mate Watch pro­vides a cli­matic over­view, in ef­fect un­til May.

Ac­cord­ing to SAWS, the rea­son for this is that the El Niño-South­ern Os­cil­la­tion (ENSO) has in the last month dras­ti­cally de­vel­oped into a cool phase, and pre­dic­tions now in­di­cate a like­li­hood of a mod­er­ate La Niña to be in ef­fect dur­ing late sum­mer.

‘The cir­cu­la­tion over the equa­to­rial Pa­cific Ocean also seems to have re­sponded to the late evo­lu­tion of a La Niña and might im­pact South Africa’s late sum­mer-rain­fall re­gions,’ said the or­gan­i­sa­tion.

‘In agree­ment with this as­sess­ment are the late sum­mer-rain­fall pre­dic­tions, in­di­cat­ing that the far north­east­ern parts of South Africa, as well as parts of the in­te­rior, are likely to re­ceive abovenor­mal rain­fall in late sum­mer.’

This should pos­i­tively im­pact lo­cal wa­ter catch­ment areas.

While po­ten­tial flood­ing re­mains a con­cern, late-sum­mer above-nor­mal rain­fall is typ­i­cally more fre­quent rather than more in­tense.

SAWS will con­tin­u­ally mon­i­tor weather pat­terns, pro­vide up­dates and is­sue warn­ings ac­cord­ingly.

‘It is ad­vised that ear­ly­warn­ing sys­tems from the SAWS be fol­lowed through­out the sum­mer sea­son.’

Cou­pled with this ex­pected rain­fall are lower late-sum­mer tem­per­a­tures than are usu­ally ex­pe­ri­enced dur­ing this time of the year.

‘In con­trast how­ever, the south-western parts of the coun­try are still ex­pected to ex­pe­ri­ence higher tem­per­a­tures on av­er­age and pos­si­bil­i­ties for hot spells are more likely dur­ing this time.’
