Drought Monitoring - National Meteorological Service of Belize
  • Residents living in flood-prone areas in the south are advised to be on the alert for the possibility of localized and flash flooding.
Tropical Weather Outlook
  • AT 3 AM: -Tropical Storm Kirk was centered near latitude 9.1 North, longitude 28.0 West. Kirk was moving W at 18 mph with maximum sustained windsof 40 mph. -The center of Tropical Depression Eleven was located near latitude 14.5 North, longitude 55.0 West. The depression was moving toward the NW at 6 mph and maximum sustained winds are near 30 mph. -NO THREAT TO BELIZE AT THIS TIME. Elsewhere, tropical cyclone formation is not expected during the next 48 hours.

Hurricane Tips
  •  Fill sinks, bathtub and large containers with water as an extra supply for washing and flushing.
  •  During the hurricane season, fisher folks are strongly advised to stay informed via radio, listen to the weather bulletin before venturing out to sea. Move your boat to safe harbor early.
  •  Prepare your car in case of evacuation. Fill your tank and check your tires.
  •  Upon alert, farmers should harvest crops which can be stored, consumed and sold.
  August 2018 |  Print Report

Conditions continued abnormally dry during July 2018, especially over nothern and central areas of the country.  Additionally, the rainfall forecast for the next three months indicate that totals will continue below normal for the north.  Therefore,  the short-term drought watch for the north is being upgraded to a drought warning.  Central areas continue under a drought watch while there is no concern for the south at this time.   See the map below.

The 12 month SPI-based drought outlook uses data through to June 2018, with potential impacts on large surface water reserves and groundwater. In general negative impacts are expected if the SPI is less than or equal to -1.3 (very dry or worse ref: CDPMN). The current 12-month SPI-based drought outlook for the country shows that there is no long-term drought concern for most of the country except for the north where a drought watch continues to be in effect.  See the map below.


Forecast Drought Condition for Belize is done using Standardized Precipitation Index (SPI)

The Standardised Precipitation Index (SPI), developed by T.B. Mckee, N.J. Doesken and J. Kleist (McKee et al. 1993) of Colorado State University is an index that, if used carefully, can provide early warning of an extended drought period and aid in assessing drought severity. It can also provide similar information at the other end of the spectrum- extremely high precipitation. SPI is basically a representation of rainfall in units of standard deviation. Positive values indicate greater than median rainfall; negative values indicate less than median rainfall. Belize is now using this tool for early drought warning.

A three-month SPI analysis reflects short to medium term moisture and can give an indication of available moisture conditions at the beginning of the growing season. A six-month SPI analysis reflects medium term trends in rainfall and is effective in showing rainfall distribution over distinct seasons as well as being associated with anomalous stream flows and reservoir levels, which takes longer to manifest itself than does agricultural drought. A twelve-month SPI can indicate the potential periods of shortfall in groundwater amounts.
