Nona was seen to be heading north east by PAGASA last night, however, the convection is more or less skewed north east with the high wind shear over the region. Overall, low level winds are flowing south west taking Nona’s low level circulation with it.
Latest data from TRMM(NASA) and GSMAP (JAXA) show that the heaviest rain has been and will continue to be over Luzon.
