(Beritadaerah – Jakarta) Badan Meteorologi Klimatologi dan Geofisika (BMKG) mengeluarkan peringatan mengenai potensi cuaca ekstrim pada periode 10-16 Februari 2021.
BMKG mencatat sebagian besar wilayah Indonesia (96 persen dari 342 Zona Musim) saat ini telah memasuki musim hujan. Hal ini juga telah diprediksi sejak Agustus 2020 lalu, bahwa terkait dengan puncak musim hujan akan terjadi pada Januari – Februari 2021 di sebagian Sumatra bagian selatan, sebagian besar Jawa termasuk DKI Jakarta, sebagian Kalimantan, Bali, Nusa Tenggara, sebagian Sulawesi, sebagian Maluku, sebagian Papua Barat dan bagian selatan Papua.
“Berdasarkan kondisi tersebut, maka kewaspadaan akan potensi cuaca ekstrem harus terus ditingkatkan,” disampaikan Deputi Bidang Meteorologi Guswanto dalam keterangan tertulisnya, Selasa (09/02).
Analisis BMKG menunjukkan bahwa kondisi dinamika atmosfer yang tidak stabil dalam beberapa hari ke depan dapat meningkatkan potensi pertumbuhan awan hujan di beberapa wilayah Indonesia.
Hal ini disebabkan oleh munculnya pusat tekanan rendah di sekitar wilayah Australia dan munculnya sirkulasi siklonik di sekitar wilayah utara Indonesia sehingga mempengaruhi pola arah dan kecepatan angin yang dapat meningkatkan potensi pertumbuhan awan hujan di sekitar wilayah Indonesia.
Selain itu, kondisi labilitas atmosfer yang kuat di sebagian wilayah Indonesia dapat turut berpengaruh signifikan terhadap pertumbuhan awan hujan dalam skala lokal.
Berdasarkan kondisi tersebut, BMKG memprakirakan dalam periode sepekan ke depan curah hujan dengan INTENSITAS LEBAT yang dapat disertai kilat/petir dan angin kencang berpotensi terjadi di wilayah Aceh, Sumatra Utara, Sumatra Barat, Jambi, Bengkulu, Sumatra Selatan, dan Lampung.
Juga di Banten, Jawa Barat, Jawa Tengah, DI Yogyakarta, Jawa Timur, Bali, Nusa Tenggara Barat (NTB), Nusa Tenggara Timur (NTT), Kalimantan Tengah, Kalimantan Selatan, Kalimantan Timur, dan Kalimantan Utara. Kemudian Sulawesi Tengah, Sulawesi Selatan, Sulawesi Tenggara, Maluku Utara, Maluku, Papua Barat, dan Papua.
Berdasarkan prakiraan cuaca berbasis dampak (Impact Based Forecast – IBF) untuk potensi dampak banjir/banjir bandang pada periode tanggal 10-11 Februari 2021 dengan status SIAGA adalah Banten, Jawa Barat, Jawa Tengah, dan
Jawa Timur.
Sementara itu, berdasarkan analisis terintegrasi dari data BMKG, PUPR, dan BIG, perlu diwaspadai daerah yang diprediksi berpotensi banjir kategori menengah pada Dasarian II Februari (sepuluh hari ke-2) di bulan Februari 2021 yaitu sebagian kecil Aceh bagian selatan, sebagian kecil Jambi bagian tengah, sebagian kecil Jawa Barat bagian timur, sebagian Jawa Tengah bagian utara, sebagian kecil Jawa Timur bagian timur, sebagian kecil Sulawesi Tengah bagian selatan, Sulawesi Selatan bagian utara, Sulawesi Tenggara bagian utara, sebagian kecil Papua Barat bagian timur dan sebagian kecil Papua bagian utara dan tengah.
Sementara itu untuk Potensi pertumbuhan Awan Cumulonimbus (Cb) di wilayah udara Indonesia dengan persentase cakupan spasial maksimum antara 50-75 persen (OCNL/Occasional) untuk periode tanggal 08-14 Februari 2021 berpotensi di wilayah Bengkulu, Lampung, Sumatra Selatan, Kepulauan Bangka Belitung, Banten, DKI Jakarta, Jawa Barat, Jawa Tengah, Jawa Timur, Bali, NTB, NTT, Kalimantan Utara, Kalimantan Timur, Sulawesi Tengah, Sulawesi Tenggara, sebagian Papua Barat, sebagian Papua, perairan barat Bengkulu, Laut Jawa, Samudra Hindia selatan Jawa, Selat Makasar, Laut Banda, dan Laut Arafuru.
Untuk Prakiraan Gelombang sepekan ked epan, dengan ketinggian 1.25-2.5 meter (kategori sedang) berpeluang terjadi di Perairan utara Sabang, Perairan barat Aceh hingga Kepulauan Nias, Perairan Bengkulu, Perairan Kepulauan Anambas – Natuna, Laut Natuna, Perairan timur Lingga – Bintan, Selat Karimata, Laut Jawa, Selat Makasar, Laut Flores, Perairan Bau-bau dan Wakatobi, Perairan Kepulauan Sermata hingga Tanimbar, Perairan selatan Kepulauan Kai – Aru, Laut Banda, Laut Sulawesi, Perairan Kepulauan Sangihe – Talaud, Laut Maluku bagian utara, Laut Halmahera, Perairan utara Papua Barat hingga Papua dan Laut Arafuru.
