When does torrential rains conditions exist?
The criteria for torrential rain vary from country to country. Torrential rain conditions is said to exist when the prevailing weather at Mauritius or Rodrigues produces 100 millimeters of widespread rains in less than 12 hours and that this heavy rain is likely to continue for several hours.
Torrential rain can cause flash floods or urban floods in any locality while the most likely effect is water accumulations in flood prone areas. Heavy rain may also be responsible for the overflow of rivulets and streams or even major rivers leading to riverine flooding. Such floods usually occur downstream where it may not be necessarily raining heavily. Another hazard in the aftermath of heavy rain is landslide which can occur on hill or mountain slopes which are usually considered as high-risk areas.
Mauritius Meteorological Services provide flood warning of a general nature without being site specific or quantifying water level in rivers.
