Why in News:
- More than a thousand families in Tripura have been displaced after their houses were submerged in flash floods that hit parts of the state.
- The floods were triggered by heavy rains, which caused the water level of river Juri and river Kakti to rise submerging houses in low-lying areas of North Tripura, Unakoti and Dhalai districts. The National Disaster Response Force (NDRF), Tripura State Rifles (TSR), firefighter team, district, and state administration have launched a joint rescue operation and have brought over a thousand people to safety. According to Skymet Weather, the rains have been attributed to the cyclonic circulation present over Northeast Bihar and a trough extending from this system to Nagaland. Another cyclonic circulation is seen over South Assam and a trough is also running from eastern parts of Bihar to North Odisha.
- Warm and moist winds are continuing over the northeastern states. Apart from these weather systems, Western Disturbance was also moving across higher latitudes.
- A flash flood is a rapid flooding of low-lying areas: washes, rivers, dry lakes and basins. It may be caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or meltwater from ice or snow flowing over ice sheets or snowfields.
