Urban flash flood are the most interminable type of unforeseen event worldwide resulting from intense storms leading to large amount of rain within a concise period. These are notably pernicious because of the short timescales on which they occur, and because of the population size of cities. Since most flood casualties are caused by a lack of information on the impending flood ,sensing such catastrophes is critical to generate authentic and detailed warnings .To provide short term forecasts to address this issue we are deploying a wireless sensor detection system to accurately detect the water level and sense the intensity of rainfall to alert the counterminous areas. This is based on the combination of arduino uno with two RF modules along with sensors .Firstly we intend to have a threefold methodology to identify a potential benefits in measuring the water level. Secondly using GSM module notification is sent via SMS and also triggers the buzzer. There are many existing technologies for flash flood measurements, but they have many drawbacks and hence give unreliable results and are not real time based. In this system the delay of the warning is less and will be operating 24 hours so that it can detect flash flood adequately and is very economical
