Signal No. 3 in Isabela, Quirino, northern Aurora due to Rosita
MANILA, Philippines – Signal No. 3 was raised in 3 areas late Monday morning, October 29, as Typhoon Rosita (Yutu) is now threatening the southern Isabela-northern Aurora area.
In a press briefing past 11 am on Monday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Rosita is already 410 kilometers east northeast of Casiguran, Aurora. It is still moving west southwest at 20 kilometers per hour (km/h).
The typhoon weakened due to its interaction with the northeast monsoon or hanging amihan. It now has maximum winds of 150 km/h from the previous 170 km/h, and gustiness of up to 185 km/h from the previous 210 km/h. But PAGASA emphasized that Rosita remains a threat, with a wide diameter of 600 kilometers.
"Pumasok na kasi 'yung amihan, so sa ngayon 'yung lamig at drier na hangin na dala ng amihan, nakaapekto sa bagyo.... Kasi ang bagyo natin warm, so kalaban niya 'yung lamig," explained PAGASA Assistant Weather Services chief Rene Paciente.
(The northeast monsoon has already begun, so the colder and drier air brought by the northeast monsoon affected the typhoon.... The typhoon has warm air, so it's in conflict with the air from the northeast monsoon.)
Below are the areas under tropical cyclone warning signals.
