The weather office today said that cyclone Biparjoy has intensified into an "extremely severe cyclonic storm". According to forecasting agencies, the storm has been undergoing "rapid intensification".
Cyclone Biparjoy is very likely to move nearly northwards and cross Saurashtra and Kutch and adjoining Pakistan coasts on June 15, the India Meteorological Department (IMD) said.
Gujarat will witness thunderstorm activity during the next five days with wind speed remaining high.
Sea conditions along and off Saurashtra and Kutch coasts will likely remain "rough to very rough" till Wednesday, and very rough to high on Thursday, the IMD said.
Tithal Beach, a popular tourist destination in Gujarat's Valsad on the Arabian Sea coast, has been temporarily closed to tourists due to high waves and strong winds.
The IMD has advised fishermen not to venture into the seas off the coast of Gujarat, Kerala, Karnataka, and Lakshadweep.
For the past week, all coastal establishments of the Indian Coast Guard have been holding regular community interactions with fishermen, and taking adequate precautions as the tropical storm brews over the Arabian Sea.
"The state governments are advised to keep a close watch, monitor the situation in their areas regularly and take appropriate precautionary measures. District authorities are advised accordingly," the IMD said.
In accordance with international maritime law, ports are required to hoist signals to alert vessels of impending adverse weather conditions. This is done to ensure the safety of maritime activities and to protect vessels and their crews.
The Pakistan government has also advised authorities in Sindh and Balochistan to remain alert. Rain accompanied by thunder is expected on the coasts of Sindh and Makran from the night of June 13, said Pakistan Meteorological Department (PMD).
