Belize is bracing for another period of heavy precipitation this weekend, as national weather authorities issued an urgent excessive rainfall warning early Saturday, October 17, 2026, forecasting an additional 2 to 4 inches of rain could fall across vulnerable regions over the next 24 hours. This new alert builds on a broader flood warning released one day earlier by the country’s Ministry of Sustainable Development and Climate Change, which had already projected 2 to 4 inches of total rainfall across a four-day window and warned of the imminent threat of flash flooding in low-lying, flood-prone communities across the nation.
Meteorologists attribute the persistent wet conditions to a lingering trough of low pressure, which is maintaining moist, unstable atmospheric conditions ideal for continued shower activity across the Belize region. Through Saturday, the sky will remain mostly overcast through both daytime and overnight hours. Saturday morning will see most precipitation—including scattered showers, light steady rain, and a handful of thunderstorms—remain concentrated offshore, but this wet activity is expected to push inland and spread across most of the country by Saturday afternoon. Overnight Saturday into Sunday, the bulk of the showers, light rain, and isolated thunderstorms will shift back to focus on coastal areas and offshore waters.
In addition to the flood and rainfall warnings, authorities have also enacted a small craft caution for all marine operators along Belize’s coast. Gusty winds that accompany heavy showers and thunderstorms can create sudden locally rough sea conditions that pose a hazard for small vessels. Current forecasts predict winds will blow from the northeast to east at 5 to 15 knots, generating a light to moderate chop with wave heights ranging between 2 and 4 feet, creating the risk of unexpectedly rough conditions during passing storm activity.
Looking ahead to Sunday, the cloud cover is expected to thin slightly, with forecasts calling for partly to mostly cloudy skies across the country. A limited number of showers, extended periods of light rain, and isolated thunderstorms will still impact most regions Sunday, before precipitation shifts primarily to coastal areas Sunday night. For temperature expectations, coastal areas will see daily highs of 86 degrees Fahrenheit (30 degrees Celsius) and overnight lows dropping to 78 degrees Fahrenheit (26 degrees Celsius). Inland regions will see warmer afternoon highs reaching 90 degrees Fahrenheit (32 degrees Celsius) with cooler overnight lows of 74 degrees Fahrenheit (23 Celsius). The cooler hill regions of Belize will see temperatures ranging between a high of 78 degrees Fahrenheit (26 Celsius) and an overnight low of 68 degrees Fahrenheit (20 Celsius).
Officials are urging all Belize residents to closely monitor changing weather conditions over the coming days and keep up to date with official emergency management and weather updates to stay safe amid ongoing flood and storm risks.
