However, the release added, because of existing borderline La Ni?a influences, this could be a ‘milder’ Dry Season than the norm.
The Met Office said that conditions such as reduced rainfall, prevalence of westerly upper-level winds and a North Atlantic Sub-Tropical High press system – which are all the criteria necessary for declaration of a Dry Season – have been met and are firmly entrenched.
The outlook for the 2017 Dry Season, the release stated, indicates impactful drying will occur most likely in late February through to March, with odds that are highest for near average rainfall totals for the season overall.
The TTMS expects the latter half of February, all of March and most of April to be particularly hot and dry with hotter than average daytime and nighttime temperatures.
As a result, there are very high odds for a large number of hot days (temperature greater than 34.00C) and relatively long periods of consecutive dry days, but especially so, during the heat season February to April. As a consequence, it is very likely that these months will produce hot spell conditions in the country.
The country can expect to see rainfall episodes occurring but not with the frequency and quantity of the transition months. Likely impacts of the 2017 Dry Season Include: reduction in ground water recharge, surface water flows and rain-fed water availability; increase in surface dryness which can lead to increase in dusty conditions; Increased browning of weeds, grass, bush and some forest species as the season progresses; drier and hotter conditions will increase bush and forest fire potential during the season; drier conditions can increase the need to collect and store water in containers which can increase breeding areas for mosquitoes.
Drier conditions have the potential to affect water reservoirs negatively which can impact the current tourism and Carnival seasons; hotter and drier conditions increase the chance for heat and water stress for crops, pastures and livestock; drier and warmer conditions tend to favour better quality in some fruits and some outdoor activities; stronger low level winds increase the potential for rough seas which can affect sea bathing and marine activities.
As such, the Met Office advised, citizens must conserve, store and manage water in a sustainable manner and take measures to reduce the effects of prolonged exposure to sunshine and dusty conditions.
It is also “highly recommended”, the release added, for the public to refrain from burning rubbish in grassy or forested areas during the Dry Season.
Relevant Agencies and Ministries are advised to take measures to mitigate the potential impacts of the current Dry Season.
