seperti diprediksi sebelumnya, aktivitas siklon tropis Nicholas terus menguat hingga mencapai kategori 2 (versi biro meteorologi australia) dengan kecepatan angin rata-rata 50 knot (95 Km / jam).

dengan menguatnya aktivitas siklon tropis Nicholas, penutupan awan di pulau jawa hingga nusa tenggara akan terus terjadi dan kemungkinan besar juga diikuti dengan turunnya hujan dengan intensitas sedang. berdasarkan laporan biro meteorologi australia, kondisi tersebut diprediksi terus bertahan hingga akhir pekan, seiring dengan pergerakan siklon ke selatan menjauh dari samudera indonesia.

REMARKS:

Although continuing to be influenced by moderate vertical shear Nicholas is showing increasing

curvature in the deep convection in both VIS and microwave imagery. A wrap of approximately

0.8 was obtained on recent VIS images to arrive at DT3.5. MET is 4.0, PAT 3.5 and hence FT is

 3.5.
Current westwards motion is likely to be replaced with a more southerly track as the anticyclone

 to the southwest weakens over the weekend, in accordance with consensus of model guidance.

 Once the system moves further south the shear should decrease and the intensification rate

may increase.
