The National Weather Service (NWS) has issued a Public Storm Warning Signal #1 over Mindanao, indicating that dangerous winds are approaching the country. The tropical depression is expected to reach severe tropical storm strength before Tuesday morning. This storm will be given the domestic name Odette when it passes inside the Philippine Area of Responsibility (PAR).


The cyclone is expected to move northwestward over the next three days, with landfall possible sometime on Tuesday.

The TCWS is a tiered system that warns of the expected winds from a tropical cyclone. Local wind strength can vary based on local topography and nearby buildings. Generally, tropical cyclone winds are stronger over the ocean and on high ground. In areas sheltered from the prevailing wind direction, local winds are weaker.
