Public Storm Warning Signal # 1

Meteorological Conditions

- A tropical cyclone will affect the locality.

- Winds of 30 - 60 kilometers per hour (kph) may be expected in at least 36
    hours or intermittent rains may be expected within 36 hours. (When the
    tropical cyclone develops very close to the locality - a shorter lead time of the
    occurrence of the winds will be specified in the warning bulletin)

Impact of the Winds

- Twigs and branches of small trees may be broken.

- Some banana plants may be tilted or downed.

- Some houses of very light materials (nipa and cogon) may be partially unroofed.

-   Unless this warning signal is upgraded during the entire existence of the tropical
    cyclone, only very light or no damage at all may be sustained by the exposed
    communities.

- Rice crop, however, may suffer significant damage when it is in its flowering
stage.

Precautionary Measures

- When the tropical cyclone is strong or is intensifying and is moving closer, this

signal may be upgraded to the next higher level.

- The waves on coastal waters may gradually develop and become bigger and
higher.

-   The people are advised to listen to the latest severe weather bulletin issued by
    PAGASA every six (6) hours. In the meantime, business may be carried out as
    usual except when floods occur.

- Disaster preparedness is activated to alert status.
