Kwajalein Atoll Forecast

KWAJALEIN FORECAST DISCUSSION
Modest shower activity is expected mainly across the southern Atoll today and tonight. The Inter-Tropical Convergence Zone (ITCZ) currently resides across the south-central RMI and will push a modest atmospheric wave through the Atoll over the next day or so. The greatest shower coverage associated with this feature will be concentrated just south of our area, so isolated to widely scattered showers can be expected across the southern Atoll with lesser coverage likely for the northern Atoll. Deeper atmospheric moisture is also present with the ITCZ, so a heavy shower or two may be possible. Additionally, mid-level temperatures may be just cold enough to generate a couple of stray lightning strikes if any deeper convection does develop. Sustained wind speeds will remain amplified in the middle to upper teens due to the tight pressure gradient across the region, with gusts in the upper 20s possible near any heavier showers. By midday tomorrow, this ITCZ is likely to recede from the region, and drier weather will temporarily return for a couple of days. Shower activity and thunderstorm potential may then see another increase toward the end of the week and this weekend as the ITCZ pushes towards the central RMI once again, but uncertainty remains. Winds look to remain elevated throughout the extended period, and they may be strong enough for a Small Craft Advisory (SCA) to need to be issued from time to time. Shower coverage will be around 15-20% today and tonight for the southern Atoll and 10-15% for the northern Atoll. Combined seas on the open ocean will be 6-8 feet. SMS
