You do get these types of trop­i­cal sys­tems com­ing down on the odd oc­ca­sion, there’s a rigid high pres­sure that moves south in sum­mer and north in win­ter and that’s what generally shields us from the trop­ics. Tom Adams

Icy tem­per­a­tures have been put on hold as Hawke’s Bay is in for some heavy down­pours over the next 24 hours.

Metser­vice me­te­o­rol­o­gist Tom Adams said the re­gion would ex­pe­ri­ence rel­a­tively warm tem­per­a­tures over the next day, but heavy rain was a big concern.

“We’re ac­tu­ally look­ing at some mild and even hu­mid tem­per­a­tures for this time of the year and that’s bring­ing some very heavy rain,” he said.

“I think what peo­ple need to be con­cerned about is the heavy rain warn­ing from 8pm tonight un­til 8am to­mor­row morn­ing where 140mm200mm of rain could ac­cu­mu­late, es­pe­cially about the ranges.”

The se­vere weather event is all thanks to mois­ture be­ing dragged down from the trop­ics and it will move rel­a­tively slowly through the re­gion, mean­ing rain is likely to ac­cu­mu­late.

Adams said heavy rain events usu­ally moved through the re­gion in a mat­ter of hours dur­ing win­ter, but with trop­i­cal events, it was a dif­fer­ent story.

“On top of that there will be some gusty winds as well, from around 1am to 3pm to­day, some south­east­erly winds might be­come se­vere, so that comes in sec­ondary with the rain, which is go­ing to be a big fac­tor for both Hawke’s Bay and Gis­borne,” he said.

While many won’t be sur­prised by rain­fall in win­ter, Adams said that a trop­i­cal weather event was fairly un­usual for this time of year.

“You do get these types of trop­i­cal sys­tems com­ing down on the odd oc­ca­sion. There’s a rigid high pres­sure that moves south in sum­mer and north in win­ter and that’s what generally shields us from the trop­ics.

“For low pres­sure to break through this ridge is very un­usual, for a global band of high pres­sure to make it down to our neck of the woods is even more un­usual and it’s worth pay­ing at­ten­tion to, be­cause it’s go­ing to be quite a sig­nif­i­cant weather event,” he said.

Hawke’s Bay Civil De­fence emer­gency man­age­ment group man­ager Ian Macdon­ald said peo­ple could ex­pect sur­face flood­ing and slips and pos­si­ble power out­ages.

“We’re not ex­pect­ing any sig­nif­i­cant flood­ing in our ma­jor rivers, but there could be some lo­calised flood­ing.

“A lot of the heavy rain will fall around the ranges, so it’s not go­ing to im­pact sub­ur­ban ar­eas too badly.”

Macdon­ald said it was a good idea for peo­ple to keep an eye on road con­di­tions as some ar­eas may ex­pe­ri­ence slips due to the heavy rain­fall.

“If peo­ple are driving the Napier-Taupo road, there may be slips around that area, but it’s also good to check the AA or the NZTA web­sites for live road updates if you’re trav­el­ling.”

The Metser­vice said the rain was due to clear this evening with sunny spells pre­dicted for to­mor­row with a high of 13 de­grees.
