Mangaluru, May 5: Meteorological experts from the IMD state that the prospect of summer rain hinges on an increase in atmospheric moisture content.

According to the IMD, summer rain becomes plausible only when the atmospheric humidity surpasses 70% relative humidity (RH). Following recent rainfall, the humidity has dropped to 40% RH. If the RH remains between 40% and 70%, the likelihood of rain diminishes. However, in Bengaluru, rainfall might occur with an RH exceeding 50%. IMD officials classify coastal districts as plains and Bengaluru as a hill station, influencing rainfall dynamics.

In the upcoming days, there are anticipations of rain due to a change in wind direction in Karnataka's interior regions and indications of low pressure in Kanyakumari and the Bay of Bengal. While there are no cyclone predictions by the IMD, consistent westerly winds persist.

Over the past two days, early morning fog has been observed in coastal districts. However, areas experiencing ample rainfall subsequently bask in sunlight. Though water remains scarce, fog formation occurs in these regions due to the residual moisture. As the sun's rays penetrate, the fog dissipates. This phenomenon, distinct from winter fog, contributes to a marginal rise in temperature and humidity, according to IMD scientists.

Weather expert Saishekar predicts a decrease in the intensity of summer rainfall, with the Malnad region likely to witness continued rain for some days. In other areas, rain can be expected only after May. Pre-monsoon signals are already apparent in the Hindu Ocean. Barring complications such as low pressure systems and cyclones, the monsoon could arrive earlier than anticipated this year.

Senior IMD scientist Prasad M D forecasts a potential rise in temperature in the coming days, with current temperatures hovering around 30 to 34 degrees Celsius post-recent rainfall. Temperatures might escalate to 38 to 40 degrees Celsius, accompanied by increased moisture levels conducive to summer rains. Interior and southern parts of the state could witness temperature spikes of two to three degrees Celsius.
