Consider the following statements:
1. The south-west monsoon causes heavy rainfall in the Shillong plateau.
2. The north-east monsoon causes the rainfall over Orissa coast during winter.
Which of these statements is/are correct ?

The south-west monsoon causes heavy rainfall in the Shillong plateau. Guwahati, being in the rain shadow of the Meghalaya plateau, receives only 1,717 mm of rain. About 90 % of the rain is received during the southwest summer monsoon, and June is by far the rainiest month. Shillong plateau with its southern limit marked by a 1,200-m-high scarp overlooking the Bangladesh plain receives very heavy rains.
