WASHI is slowly strengthening… Satellite appearance of the storm has improved noticeably… Convective bands wraps more than 0.75 on log10 spiral closely into the circulation centre… Upper level outflow remains good… Vertical wind shear is still weak and favourable for development… WASHI should go on intensifying before it crosses the Philippines and moves into the South China Sea where intense northeasterly flow prevails…
