A regional team of meteorologists and other climate scientists are warning that the Caribbean faces another busy wet/hurricane season this year, with an expected 18 to 19 named storms.

They also caution that government and other decision-makers should prepare for hazards such as flooding/flash flooding and landslides to minimise socio-economic disruptions, particularly in the second half of the season.

That announcement was made during the virtual forecast delivery for the 2022 Wet/Hurricane Season Caribbean Climate Outlook Forum (CariCOF), hosted by the Caribbean Institute for Meteorology and Hydrology (CIMH) in collaboration with national hydrometeorological services (NHMSs), the National Oceanic and Atmospheric Administration (NOAA), Columbia University’s International Research Institute (IRI) for Climate and Society, and the World Meteorological Organization (WMO).

The wet/hurricane season officially starts annually on June 1 and ends on Nov. 30.

This year’s forecast would mark the seventh consecutive year of an above-average season for the region.

The situation of high tropical cyclone activity and excessive rainfall is likely being enhanced by an extended La Niña that should extend into the summer. The conditions could result in up to nine hurricanes of which four could be major, according to Colorado State University.

“Governments, sectors, communities and other interests should prepare for the implications of expected conditions during the 2022 wet/hurricane season, such as floods and cascading hazards, frequency of tropical cyclones higher than average, a decrease in the frequency of dry spells, and extreme heat peaking between August and October (though not as strong as in recent years),” Chief of Applied Meteorology and Climatology at CIMH, Adrian Trotman said.  

CIMH also announced a set of key messages on this year’s predicted seasonal activity intended to alert policymakers and other authorities to take steps to protect property, lives, public health and safety.

The key messages were organized between the first half and second half of the season, as follows:  

June-July-August 2022

  • Heat discomfort will increase towards August. Heat stress will peak during heatwaves. However, not likely to be as hot as recent years.
  • Progressively stronger tropical cyclone activity into August.
  • Flash flood and long-term flooding potential will increase from moderate to high by August in the islands but should remain high in the Guianas.
  • Flood potential particularly high between 3-9 June in the coastal Guianas, extending recent concerns of flooding particularly in Suriname.
  • Drought is not expected to be a major concern. However, those currently experiencing drought may still see impacts in early portions of this period.

September-October-November 2022

  • Strong tropical cyclone activity through October and, likely, more active than normal.
  • Heat impact potential peaking in September, with cooler temperatures expected from November onwards, when heat discomfort should sharply decrease. Not expected to be as hot as recent years.
  • The potential for flooding and flash floods is high and should be of particular concern if the La Niña persists.
  • Region-wide, long-term drought is not expected to be a major concern by the end of November.

CIMH, which also operates the World Meteorological Organization (WMO) designated Caribbean Regional Climate Centre (RCC), advised stakeholders to check their website for updated information throughout the season.

Following the forecast delivery, experts gathered with sectoral representatives to discuss how expected conditions can impact climate-sensitive sectors such as agriculture and food security, disaster management, health, energy, tourism, water resource management.

They also addressed how those sectors can effectively engage in contingency planning to prevent loss of economic productivity and livelihoods.

CariCOF is hosted twice a year by CIMH ahead of the start of the region’s wet and dry seasons. During the bi-annual event, Caribbean meteorologists and other climate scientists gather for training, discussions and the preparation of seasonal forecasts and other products.

    I hope the Huricanes wash out the crooked wutliss set of greedy politicians around the place these days.
