The normal onset date of Southwest Monsoon over Kerala is June 1. However, invariably Monsoon arrives over the state before or after its normal onset date. Now also, Monsoon is yet to mark its onset in Kerala.
Prior to onset of Monsoon, pre-Monsoon weather activities pick up pace and the entire state of Kerala experiences intense rain showers. The reason for this is associated with the terrain of the state.
Even though normally during the pre-Monsoon season, the state witnesses good pre-Monsoon rain and thundershower activities. However, this season, weather activities remained on the lower side and Kerala is rain deficient by almost 55% for the season so far.
As per Skymet Weather, Monsoon is expected to mark its onset over Kerala around June 7. Thus, pre-Monsoon weather activities have already started picking up pace in most parts of the state. In fact, since the beginning of June, rain and thundershowers are being observed in Kerala.
During the last 24 hours, fairly widespread light to moderate rains with few heavy spells occurred in parts of Kerala. In the last 24 hours from 08:30 am on Sunday, Alappuzha recorded 58 mm of rain, followed by Thiruvananthapuram 33 mm, Kottayam 22 mm, Kochi 9 mm and Punalur 3 mm.
Now in the coming days, we expect pre-Monsoon rainfall activities to pick up pace over Kerala. Hence, during the next 48 hours or so, we expect moderate rains with heavy spell and strong winds to occur in most parts of the state.
In fact, till the onset of Southwest Monsoon over Kerala, weather conditions over the state will not go completely dry and rains of varying intensity will occur in parts of Kerala.
