      TROPICAL DEPRESSION HANNA (98W) 
      MAY BRIEFLY BECOME A TROPICAL STORM
      BASED ON THE LATEST 6:57 AM SATELLITE IMAGERY, BEFORE MAKING LANDFALL
      OVER AURORA THIS MORNING.

      + FORECAST OUTLOOK: HANNA is expected to move WNW within 12 hours and
      cross Luzon via Aurora this morning and shall pass over the provinces
      of Quirino, Benguet & La Union this afternoon. The ill-defined center
      of HANNA shall be off the coast of La Union tonight and be over the
      South China Sea early tomorrow morning (Sunday Sep 30)

      + EFFECTS: HANNA's rain bands continues to spread across the island of
      Luzon becoming more intense along the Eastern and Central sections
      particularly along mountain slopes of Sierra Madre Mountains (along
      Northern Quezon-Aurora-Isabela Area). Cloudy skies with widespread
      rains can be expected along these bands. People living around the
      slopes of Mayon Volcano in Albay especially along the area where po-
      ssible LAHAR FLOWS (mixture of volcanic mud and water) are located -
      must stay alert as moderate to heavy rains are possible today. Flash
      floods and mudslides are imminent along river banks, low-lying and
      mountainous regions of the affected areas. Precautionary measures
      must be initiated as the depression approaches.

      + CURRENT ITCZ/MONSOON INTENSITY: Active ITCZ (Monsoon Trough) embedded
      along the wet-phase of the Madden-Julian Oscillation (MJO) will con-
      tinue to bring cloudy skies with rainshowers & thunderstorms across
      the Philippines becoming more frequent over the eastern & central
      sections of the country. Landslides and flooding is likely to occur
      along steep mountain slopes, river banks, low-lying & flood-prone
      areas of the affected areas. Southwest (SW) Monsoon enhanced by HANNA,
      currently affecting Western & Southern Mindanao, Western Visayas,
      Palawan and Sulu Sea.
       
      Important Note: Please keep in mind that the above forecast outlook,
      effects & current monsoon intensity, and tropical cyclone watch changes 
      every 06 to 12 hours!
