The combination of moisture meeting cold air led to what is called "cyclogenesis" - the birth of a new storm.
Where cyclogenesis occurs, precipitation is enhanced.
Tropical cyclones, which form over warm tropical waters, are less frequent in spring since sea temperatures are generally too low for cyclogenesis.
